# How do you simplify 3 1/6 + 4 1/4?
Jul 16, 2016
#### Explanation:
To add the two numbers we may observe that:
$3 \frac{1}{6} = 3 + \frac{1}{6}$, and similarly
$4 \frac{1}{4} = 4 + \frac{1}{4}$. Now we can add and rearrange:
$3 \frac{1}{6} + 4 \frac{1}{4} = 3 + \frac{1}{6} + 4 + \frac{1}{4} = 3 + 4 + \frac{1}{6}... | HuggingFaceTB/finemath | |
