A division of a whole called fraction. Fractions can be creating of minimum two numbers. The numerator specified as top number. The denominator specified as bottom number.

Understanding What is a Fraction? is always challenging for me but thanks to all math help websites to help me out.

In mathematics, ten as it base called as decimal number system. The numbers using the base-10 numeral system specified as decimal notation. A dot with a decimal number, like to present in 0.287. Here we are going to see about write fraction as a decimal.

Examples problem for write fraction as a decimal:

1. Write fraction as a decimal, given fractions are i) `2/10` and ii) `9/10` .

Solution:

Given fractions, i) `2/10`

`= 2/10`

The 2 divided by 10, we get the decimal value is,

`= 0.2`

The fraction, `2/10` gives the decimal is 0.2 (two tenths).

Given fractions, ii) `9/10`

`= 9/10`

The 9 divided by 10, we get the decimal value is,

`= 0.9`

The fraction, `9/10` gives the decimal is 0.9 (nine tenths).

2. Write fraction as a decimals correct to two decimal places, given fractions are i) 75/20 and ii) 52/36

Solution:

Given fractions, i) `75/20`

`= 75/20`

The 75 divided by 20, we get the correct to two decimal places is,

`= 3.75`

The fraction, `75/20` gives the decimal is 3.75 (three and sevety-five hundredths).

Given fractions, ii) `52/36`

`= 52/36`

The 52 divided by 36, we get the correct to two decimal places is,

`= 1.44`

The fraction, `52/36` gives the decimal is 1.44 (one and forty-four hundredths).

3. Write fraction as a decimals, correct to three decimal places, given fractions are i) `88/48` and ii) `27/8`

Solution:

`= 88/48`

The 88 divided by 48, we get the correct to three decimal places is,

`= 1.833`

The fraction, `88/48` gives the decimal is 1.833 (one and eight hundred thirty-three thousandths).

Given fractions, ii) `27/8`

`= 27/8`

The 27 divided by 8, we get the correct to three decimal places is,

`= 3.375`

The fraction, `27/8` gives the decimal is 3.375 (three and three hundred seventy-five thousandths).

I am planning to write more post on Convert a Fraction to a Decimal and how to simplify large fractions. Keep checking my blog.
