## What is the Definition of an Equivalent Decimal

### Equivalent Decimals

Decimals are a type of fractional number. The decimal 0.2 represents the fraction $$\frac{2}{10}$$. We know $$\frac{2}{10}$$ is equivalent to $$\frac{1}{5}$$, since $$\frac{1}{5}$$ times of $$\frac{2}{2}$$ is $$\frac{2}{10}$$.
Therefore, the decimal 0.2 is equivalent to $$\frac{1}{5}$$ or $$\frac{2}{10}$$ or $$\frac{20}{100}$$ or $$\frac{200}{1000}$$ etc.

Observe the following diagrammatic representation:

All these three decimals i.e., 0.2, 0.20, and 0.200, have the same value and so they are called equivalent decimals.
Example 1: Give next two decimal numbers in the sequence:
(a) 1.32, 1.42, 1.52, …, …
(b) 1.14,1.25, 1.36, …, …
Solution:
(a) 1.32,1.42,1.52,1.62,1.72
(b) 1.14,1.25,1.36,1.47,1.58

Writing or removing zeros at the end of the decimal does not change its value.
Examples
0. 5 =0.50 = 0.500
= 0.5000 = 0.50000
6.2 = 6.20 = 6.200
= 6.2000 = 6.2000

Example 2: Write the number name for 207.652.
Solution: 207.652 = Two hundred seven point six five two

Example 3: Write the decimal fraction 35.439 in expanded form.
Solution:
