Table of 40 – Multiplication Chart, Tricks & Uses

Children must remember the table of 40 from 1 to 10 which is given below: 

Verdict Shortcuts to Memorise Table of 40

• The most common trick for memorising any table is to read it as loud as you can. Once you dwell on the rhythm of the table, the multiplication table of 40 gets fixed in your mind. 

• The other common trick to remembering the table of 40 is following its pattern. We know that 40 = 4 × 10. Therefore, if we multiply the table of 4 by 10, we can easily get the table of 40. 

To understand it better, let's look at the below-given table chart.

In simple language, adding zero (0) to the last digit of 4’s table will result in the multiplication table of 40.

By this trick, we can easily observe whether a given number is divisible by 40 or not. As 40 = 4 × 10, any number which is divisible by 4 and 10, will also be divisible by 40.

Question 1: There are 2 rows in the garden. In each row, a gardener has to plant 40 seeds. How many seeds does he have to plant in the garden?

Solution: Given, the number of rows in the garden = 2

Number of seeds to grow in each row = 40

Total number of seeds to grow in the garden = number of rows in the garden × number of seeds to grow in each garden

Total number of seeds to grow in the garden = 2 × 40 = 80

Therefore, the gardener has to grow 80 seeds in the garden.

Question 2: In a luggage van, 2800 boxes are loaded. The distributor wants to segregate these boxes equally in small 40 vans. How many boxes will each small van carry?

Solution: Given, boxes loaded in huge van = 2800

Number of small vans = 40

To distribute 2800 boxes in the 40 small vans, we have to divide 2800 by 40.

So, the number of boxes in each small van =\[\frac{2800}{40}=70\].

Therefore, the distributor has to load 70 boxes in each small van. 

Question: Solve the following number problems:

1. 68 × 40 = 

2. 5400 ÷ 40 = 

3. 40 × … = 9800

Answers: 

1. 68 × 40 = 2720

2. 5400 ÷ 40 = 135

3. To solve this question 40 × … = 9800, we have two methods:

First method: In this method, we have to think by which number we should multiply 40, to get 9800. For that, we will count the table to 40. Since we know the table of 40 from 1 to 10, we will not be able to solve this problem by this method. (Do not get sad, we will keep this point in mind and use it further.)

Second method: In this method, we divide the number on the right-hand side, i.e., 9800 by the number on the right-hand side, i.e., 40. Therefore, we get 9800/40=245

So, 245 is the required answer.

(Verify the answer: To verify whether 245 is the correct answer or not, we can use method 1. Let's multiply 40 by 245, if the resultant number is 9800 then we get the right answer.)

MCQs

Question 1: What is 8 times of 40?

1. 210

2. 600

3. 480

4. 320

Answer: d

Explanation: 8 times of 40 = 8 × 40 = 320

Therefore, the correct answer is (d).

Table Chart of 40 from 11 to 20

Learning the table of 40 is not a big task as you can easily memorise it by the table of 4. We request you to learn the table of 40 up to 20 to solve complex mathematical problems easily. Here, the table of 40 from 11 to 20 is given, just read it and try to memorise it. 

Wrapping It All Up!

Tables are the most crucial components of Mathematics. Learning tables will not only help to solve complex mathematical calculations easily but also develop a habit of memorising a large amount of data in their mind.

Though teachers advised students to learn tables from 1 to 20, we request them to develop a habit to learn more tables.
