Answer 1

а)

$2 \frac{3}{8} \times \frac{3}{19} \times 1 \frac{1}{9} a = \frac{19}{8} \ \times\frac{3}{19} \times \frac{11a}{9} = \frac{19 \times 3 \times 10a}{8 \times 19 \times 9} = \frac{1 \times 1 \times 5a}{4 \times 1 \times 3} = \frac{5a}{12}$

б)

$\frac{3}{8} p \times \frac{4}{9} k = \frac{3p \times 4k}{8 \times 9} = \frac{p \times k}{2 \times 3} = \frac{pk}{6}$
