Use of Decimal to Represent Money

We use decimals everyday while dealing with money. While writing rupee and paise, we use point to separate rupee from paise. We call this dot the decimal point. We can write rupees and paise as decimal numbers. Paise is always written as a 2-digit number.

We use symbol

to express rupees and paise together in decimal number.

We know that 100 paise =

1. So, 1 paise =

¹⁄₁₀₀ =

0.01

So, 50p = ¹⁄₁₀₀ × 50 =

0.05

10p = ¹⁄₁₀₀ × 10 =

0.1

So, to convert paise into rupees, we place decimal after 2 digit from the right. To convert rupees and paise into paise, we remove the decimal point.

For example,

11.45 = 11.15 × 100 p = 1145p

Solved Examples on Use of Decimal to Represent Money:

Write 7 rupees 3 paise in the form of rupees using decimal rotation.

Solution:

7 rupees 3 paise =

7.03
