Question

1 1/4 * 1 1/5 * 1 1/6 * 1 1/7 * 1 1/8 -1/4

Answer 1

$1 \frac{1}{4} \times 1 \frac{1}{5} \times 1 \frac{1}{6} \times 1 \frac{1}{7} \times 1 \frac{1}{8} - \frac{1}{4} = \frac{5 \times 6 \times 7 \times 8 \times 9}{4 \times 5 \times 6 \times 7 \times 8} - \frac{1}{4} = \frac{9}{4} - \frac{1}{4} = \frac{9 - 1}{4} = \frac{8}{4} = 2$
