Answer 1

ANSWER:

$10 \frac{22}{45}$

EXPLANATION:

$2 \frac{3}{5} + 7 \frac{8}{9}$

$= \frac{13}{5} + \frac{71}{9}$

L.C.M = 45

$= \frac{13( \times 9)}{5( \times 9)} + \frac{71( \times 5)}{9( \times 5)}$

$= \frac{117}{45} + \frac{355}{45}$

$= \frac{117 + 355}{45}$

$= \frac{472}{45}$

$= 10 \frac{22}{45}$
