Question

2 1/7×2 4/5+7 6/7×2 4/5​

Answer 1

$2 \frac{1}{7} \times 2 \frac{4}{5} + 7 \frac{6}{7} \times 2 \frac{4}{5} = \frac{15}{7} \times 2 \times \frac{4}{5} + \frac{55}{7} \times 2 \times \frac{4}{5} = \frac{3}{7} \times 2 \times 4 + \frac{11}{7} \times 2 \times 4 = \frac{24}{7} + \frac{88}{7} = 16$
