$15 \frac{1}{10}$ $15 1/10$

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

Add the whole numbers and add the numerators.

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

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

However we now have more than a whole number.

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

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