How to remove decimal point?

To do :

We have to find out how to remove the decimal point.

Solution :

To remove the decimal point we have to convert it into a rational number.

To convert a decimal to a rational number follow these steps:

Step 1: Write down the decimal divided by 1.

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

Step 3: Simplify (or reduce) the Rational number.

For example:

Convert 0.75 to a Rational number

Step 1: Write down 0.75 divided by 1.

$\frac{0.75}{1}$

Step 2: Multiply both top and bottom by 100 (because there are 2 digits after the decimal point, so that is $10\times10=100$)

$\frac{0.75\times100}{1\times100} = \frac{75}{100}$.
