Exercise 6.1

1. Write opposite of the following:

(i) Increase in weight

Ans: Opposite of a statement means something that conveys the exact reverse sense.

The given statement is, ‘Increase in weight’. This means that the amount of weight is rising. The opposite of this would be that the amount of weight is reduced. This means that the opposite of increase is decrease. So, the opposite of the given statement will decrease in weight. Therefore, the opposite of the given statement, ‘Increase in weight’ is ‘Decrease in weight’.

(ii) 30 km North

Ans: Opposite of a statement means something that conveys the exact reverse sense.

The given statement is, ’30 km North’. This means that the direction is 30 kms towards the North. The opposite of this would be that the direction is 30 km towards the South. This means that the opposite of North is South. So, the opposite of the given statement will be 30 km South. Therefore, the opposite of the given statement, ‘’30 km North’ is ‘’30 km South’.

(iii) 326 BC

Ans: Opposite of a statement means something that conveys the exact reverse sense.

The given statement is, ’326 BC’. This means 326 years before Jesus Christ was born. The opposite of this would be 326 years after Jesus Christ was born which is known as 326 AD. This means that the opposite of BC is AD. So, the opposite of the given statement will be 326 AD. Therefore, the opposite of the given statement, ‘326 BC’ is ‘326 AD’.

(iv) Loss of Rs. 700

Ans: Opposite of a statement means something that conveys the exact reverse sense.

The given statement is, ‘Loss of Rs. 700’. This means that the amount of Rs. 700 is lost. The opposite of this would be that the amount of Rs. 700 is gained which is known as profit. This means that the opposite of loss is profit. So, the opposite of the given statement will be profit of Rs. 700. Therefore, the opposite of the given statement, ‘Loss of Rs. 700’ is ‘Profit of Rs. 700’.

(v) 100 m above sea level

Ans: Opposite of a statement means something that conveys the exact reverse sense.

The given statement is, ‘100 m above sea level’. This means that the distance is over the sea level by 100 m. The opposite of this would be that the distance is beneath the sea level by 100 m. This means that the opposite of above is below. So, the opposite of the given statement will be 100 m below sea level.

Therefore, the opposite of the given statement, ‘100 m above sea level’ is ‘100 m below sea level’.

2. Represent the following numbers as integers with appropriate signs.

(i) An aeroplane is flying at a height two thousand meters above the ground.

Ans: Integer is a set of both positive and negative numbers including 0.

The given statement is, ‘An aeroplane is flying at a height two thousand meters above the ground’.

The numerical part in the given statement is 2000 m.

We will now assign a sign system to denote the given number with a sign and make it integer.

Let us assume that the height above the ground level is positive and the height below the ground level is negative. Here the ground level is taken as the zero level.

Since the airplane is flying above the ground level at a height of 2000 meters, the distance will be taken as positive.

Therefore, the representation of the number as an integer with the sign is $\left( + \right)2000\,\text{m}$.

(ii) A submarine is moving at a depth eight thousand meters below the sea level.

Ans: Integer is a set of both positive and negative numbers including 0.

The given statement is, ‘A submarine is moving at a depth eight thousand meters below the sea level’.

The numerical part in the given statement is 8000 m.

We will now assign a sign system to denote the given number with a sign and make it integer.

Let us assume that the height above the ground level is positive and the height below the ground level is negative. Here the ground level is taken as the zero level.

Since the submarine is moving below the sea level at a depth of 8000 meters, the distance will be taken as negative.

Therefore, the representation of the number as an integer with the sign is $\left( - \right)8000\,\text{m}$.

(iii) A deposit of rupees two hundred.

Ans: Integer is a set of both positive and negative numbers including 0.

The given statement is, ‘A deposit of rupees two hundred’.

The numerical part in the given statement is Rs. 200.

We will now assign a sign system to denote the given number with a sign and make it integer.

Let us assume that the deposit of rupees is positive and the withdrawal of rupees is negative. Here the current balance will be considered as zero and any transaction will be made against it.

Since Rs. 200 is deposited, the transfer will be taken as positive.

Therefore, the representation of the number as an integer with the sign is $\left( + \right)200\,\text{Rs}\text{.}$

(iv) Withdrawal of rupees seven hundred.

Ans: Integer is a set of both positive and negative numbers including 0.

The given statement is, ‘Withdrawal of rupees seven hundred’.

The numerical part in the given statement is Rs. 700.

We will now assign a sign system to denote the given number with a sign and make it integer.

Let us assume that the deposit of rupees is positive and the withdrawal of rupees is negative. Here the current balance will be considered as zero and any transaction will be made against it.

Since Rs. 700 is withdrawn, the transfer will be taken as negative.

Therefore, the representation of the number as an integer with the sign is $\left( - \right)700\,\text{Rs}\text{.}$

As discussed in Class 6 Chapter 6, integers are the collection of whole numbers(0,1,2,3..) and the negative numbers(-1,-2,-3..). Numbers with no sign are called positive integers and numbers with a minus sign are called negative integers. Negative Integers can be used to denote temperatures, water levels in lakes, outstanding dues, etc. Integers are a new concept for Class 6 students and they should understand the basics of this chapter thoroughly as it will be useful for future classes.

2. What are the different types of integers and why are they useful?

The whole numbers and negative numbers collectively are called integers. There are two types of integers that are positive and negative. Positive numbers are written as such while negative integers are written with a minus sign in front. The concept of integers is very important because sometimes the use of a negative quantity is required, for example, the water level in lakes.

3. How do you simplify the Integers Class 6?

Integers can be a tricky concept for students of Class 6 in Chapter 6. However, it can be made easy by using the number line. The number line shows all the numbers, positive and negative, which makes it easier for students to visualize them. The number line has points at equal distances with zero at the centre. The numbers on the right side of zero are the positive integers and the numbers on the left side are the negative integers.

4. How do you learn integers easily?

Integers can be taught to students by showing them on a number line and explaining with real-life examples. As it is an advanced concept, students may find it a little difficult to understand. However, explaining with examples given in NCERT will help them in applying the concepts to real problems and they will gain confidence in this chapter. Practising the exercise questions will further strengthen their fundamentals. You can use the solutions available on the official website of Vedantu or the Vedantu App. All the resources are available free of cost.

5. How do you add and subtract integers?

The following rules are followed while adding and subtracting integers-

On adding two positive integers, we get a positive integer

On adding two negative integers we get a negative integer.

When a positive and negative integer is added we subtract them as whole numbers and put the sign of the bigger number to the subtraction solution. The bigger number is the one that is big irrespective of the sign.
