## FAQs on RS Aggarwal Solutions Class 7 Chapter-3 Decimals (Ex 3C) Exercise 3.3

**1. What is a decimal and what are its types as mentioned in Class 7 RS Aggarwal solutions?**

Algebra deals with decimals. They are numbers that are divided into a number and fraction part by a point also known as a decimal point. For example, in 35.5, 35 is a whole number and 5 is a decimal whereas, “.” is the decimal point separating both. There are two types namely, recurring and non-recurring decimals. Recurring decimals are repeating and non-terminating decimals. For example, 34.4444444 is a recurring decimal. Non -recurring decimals are non-repeating or non-terminating decimals. For example, 35.4535. They are again divided into infinite and finite decimals based on their solution.

**2. What is the place value in decimals as mentioned in Class 7 RS Aggarwal solutions?**

Place value is used to define the position of a digit in the whole number. They, in turn, decide the value of the number. For example, in the number 546, 5 is in the hundreds place, 4 is in the tens place and 6 is in one’s place. When we move from left to right, the value of the number increases by ten times and when we move from right to left, the value of the number decreases 10 times.

**5. How to convert a fraction into a decimal and vice versa as mentioned in Class 7 RS Aggarwal solutions?**

Decimals after the decimal points are represented by their place values. To convert decimal to fraction, write down decimal numbers and expand them according to the place value and simplify them. To convert a fraction into a decimal, just simply solve the fraction. For example, fraction ¼ when converted to decimal results in 0.25.
