Comparing Decimals and Fractions
To compare a decimal and a fraction,
first convert, or change, one of the numbers so that we have either two decimals or two fractions. Then, compare as usual.
For example: Let’s compare
1 2
and 0.72.
First, let's write the fraction as a decimal.
Write
1 2
as an equivalent fraction with 10 as the denominator.

|
= |
|
Now, write
5 10
as a decimal.
|
= | 0.5 |
| So, |
|
= |
|
= | 0.5 | . |
Now, compare 0.5 and 0.72.
As the tenth digit of 0.5 is less than the tenth digit of 0.72,
0.5 < 0.72
| So, |
|
< | 0.72 | . |
