Question

2 2/5×6 1/4-5 1/3×1 1/8

Answer 1

$2 \frac{2}{5} \times 6 \frac{1}{4} - 5 \frac{1}{3} \times 1 \frac{1}{8} = 9 \\ 1) \: 2 \frac{2}{5} \times 6 \frac{1}{4} = \frac{12 \times 25}{5 \times 4} = 3 \times 5 = 15 \\ 2) \: 5 \frac{1}{3} \times 1 \frac{1}{8} = \frac{16 \times 9}{3 \times 8} = 2 \times 3 = 6 \\ 3) \: 15 - 6 = 9$
