Use of Decimal in Calculating Money

We will learn the use of decimal in calculating money.

As we already know that,

100 cents = 1 dollar or 100 ¢ = $ 1

So, one cent is one hundredths of a dollar.

or, 1 ¢ = $ \(\frac{1}{100}\) = $ 0.01

Similarly, 10 ¢ = $ 0.10                    (10 cents is ten hundredths of a dollar)

             50 ¢ = $ 0.50                    (50 cents is fifty hundredths of a dollar)

Dollars and cents can be expressed together as decimals.

For example,

8 dollars 25 cents = $ 8.25

24 dollars 96 cents = $ 24.96

25 dollars 40 cents = $ 25.40

120 dollars 29 cents = $ 120.29

10 dollars 5 cents = $ 10.05

238 dollars 03 cents = $ 238.03

Note: In a decimal, cents are always written in double figures.

For example, 5 ¢ = $ 0.05 and 9 ¢ = $ 0.09

Addition and subtract of money is same like addition and subtraction of decimal and whole number.
