Question

7/8*16=
3/4*3/5=
4/7*21/16=
6 2/3*1 1/5=

Answer 1

$\frac{7}{8} \times 16 = 7 \times 2 = 14 \\ \frac{3}{4} \times \frac{3}{5} = \frac{3 \times 3}{4 \times 5} = \frac{9}{20}$

$\frac{4}{7} \times \frac{21}{16} = \frac{3}{4} \\ 6 \frac{2}{3} \times 1 \frac{1}{5} = \frac{20}{3} \times \frac{6}{5} = 4 \times 2 = 8$
