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
