Jan 5, 2017

The result is $1 \frac{1}{4} s$

#### Explanation:

To add or subtract mixed numbers you can:

• change the mixed numbers to improper fractions:

$2 \frac{5}{8} - 1 \frac{3}{8} = \frac{21}{8} - \frac{11}{8} = \frac{10}{8} = \frac{5}{4} = 1 \frac{1}{4}$

• subtract whole numbers and fractions seperately:

$2 \frac{5}{8} - 1 \frac{3}{8} = \left(2 - 1\right) + \left(\frac{5}{8} - \frac{3}{8}\right) = 1 + \frac{2}{8} = 1 + \frac{1}{4} = 1 \frac{1}{4}$
