Objective:
At the end of this lesson, students should be able to write decimals as fractions.
Decimals can be written as fractions by using an approach similar to the knowledge used when changing fractions to decimals.
Example 1
Write the following decimals as fractions.
a) 0.7 (b) 0.53 (c) 0.739
Solution
Example 2
Change to fractions:
(a)3.5 (b) 7.45 (c) 18.097
Solution
NB: Always reduce fractions to their lowest (simplest) term when writing decimals as fractions.
