Changing decimals to fractions
The following are the steps to solve problems on changing decimals to fractions:
Step 1: Remove the decimal number and divide by ten, hundredth, thousandth, ten thousandths, etc.
N/b: if there is only one digit after the decimal point we divide by ten. If there are two digits we divide by hundredth and so on. We divide according to the number of the digits.
Examples:
Write the following decimals as fractions :
(a)3.20 (b)0.25
(c)7.29 (d)3.7
Solutions
3.20 = 3+0.20
since there are only 2 digits after the decimal point we remove the decimal point and divide by 100
Additions and subtractions of decimals
Decimal numbers can be added or subtracted if they are of the same decimal place.
Simplify the following:
(a)10.63 + 6.32
(b)14.354 + 23.201
(c)11.21 + 50 + 0.7
(d) 74.3 + 2.24
Simplify the following:
- 56.80 - 12.13
- 151.556 - 134.325
- 76 - 33.496
