Comparing Decimals with Mixed Numbers
7,919 Plays
To compare a decimal and a mixed number,
first convert, or change, one of the numbers so that we have either two decimals or two mixed numbers (or two fractions). Then, compare as usual.
For example: Let’s compare 4
1 5
and 4.13.
First, let's write the mixed number as a decimal.
In order to do so, we first write the fractional part of the mixed number,
1 5
, as a decimal.
Write
1 5
as an equivalent fraction with 10 as the denominator.

Now, write
2 10
as a decimal.
|
= | 0.2 |
| So, | 4 |
|
= | 4.2 | . |
Now, compare 4.2 and 4.13.
As the tenth digit of 4.2 is greater than the tenth digit of 4.13,
4.2 > 4.13
| So, 4 |
|
> | 4.13 | . |
