Answer 1

а)

$5 \frac{3}{16} \times 32 = \frac{83}{16} \times 32 = \frac{83 \times 32}{16} = 166$

б)

$2 \frac{1}{3} \times 15 = \frac{7}{3} \times 15 = \frac{7 \times 15}{3} = 35$

в)

$1 \frac{3}{8} \times 2 = \frac{11}{8} \times 2 = \frac{11 \times 2}{8} = \frac{11}{4}$

г)

$4 \frac{7}{19} \times 19 = \frac{83}{19} \times 19 = \frac{83 \times 19}{19} = 83$
