In real number, there are infinite numbers that can be written in both fractions and decimals. Knowing how to convert the numbers, can help you to make the simplification simpler. In fraction, the rules for doing certain operations is very different from that of decimals. To an extend decimal calculation is an extension of the methods used in whole number calculation. Fraction are sometimes difficult to calculate as they involve denominator terms, so converting the fractional forms to decimal is very important. Many methods can be used to convert any fraction to decimal, by which computation of operations with real numbers becomes much simple.

## How to Convert Fractions to Decimals

**Denominator contains $10$, $100$,..........**

In this method, if any of the fractions contains the number like 10, 100... etc in the denominator, then just count the number of zeros and move the decimal point in the numerator to the right side.**For example**$ \frac{2}{10 }$ = 0.2**Change to equivalent fractions with denominator 10, 100….**

In this method, the denominator may not contain 10, 100 etc but we can convert them into equivalent fractions in which the denominators contains 10, 100 etc.**For example**$ \frac{5}{25 }$

Here denominator = $25$

If we multiply $4$ we get $25*4 = 100$

So multiply $4$ on top and bottom of $ \frac{5}{25}$

Hence $\frac{5}{25}$*$\frac{4}{4}$= $ \frac{20}{100}$

Now it can be converted to decimal as

So $ \frac{5}{25}$ = $0.2$**Divide numerator by denominator**

There are certain fractions that cannot be changed to an equivalent fractions. In such situation we divide numerator by the denominator.**For example**, $ \frac{4}{8}$

Divide $4$ by $8$.

Here numerator = $4$ is less than the denominator = $8$

So we take a decimal point to the quotient and change 4 to 40.

Here numerator = $40$ is greater than the denominator = $8$

Taking the multiples of 8, we get $8*5=40$

So answer to $ \frac{4}{8}$ = $0.5$

## Change Fractions to Decimals

### Solved Examples

**Question 1:**Convert $\frac{8}{100}$ to decimal.

**Solution:**

Given $\frac{8}{100}$

numerator = 8 and denominator = 100

Here denominator contains hundredths place

So $\frac{8}{100}$ = 0.08.

numerator = 8 and denominator = 100

Here denominator contains hundredths place

So $\frac{8}{100}$ = 0.08.

**Question 2:**Convert $\frac{2}{7}$ to decimal.

**Solution:**

Given $\frac{2}{7}$

$\frac{2}{7}$ = 2 ÷ 7

= 0.29

$\frac{2}{7}$ = 2 ÷ 7

= 0.29
