# How do you evaluate 8 13/20 + 6 9/20?

Aug 1, 2016

$15 \frac{1}{10}$

#### Explanation:

As the denominators are already the same we can just add.

Add the whole numbers and add the numerators.

$8 \frac{13}{20} + 6 \frac{9}{20}$

=$14 \frac{13 + 9}{20} = 14 \frac{22}{20}$

However we now have more than a whole number.

$14 + 1 \frac{2}{20}$

=$15 \frac{2}{20} = 15 \frac{1}{10}$
