Answer 1

Ответ:

$1) \frac{5(bc + m)}{2q + 4 \frac{1}{4} } = \frac{5( \frac{2}{3} \times 6 + \frac{1}{5} )}{2 \times \frac{1}{2} +4 \frac{1}{4} } = \frac{5 \times 4 \frac{1}{5} }{1 + 4 \frac{1}{4} } = \frac{5 \times 21}{5} \div \frac{21}{4} = \frac{21 \times 4}{21} = 4$

$2) \frac{3(x - y)}{2p + q} - 1 = \frac{3(8 . 31 - 2.29)}{2 \times 2.01 + 2} - 1 = \frac{3 \times 6.02}{4.02 + 2} - 1 = \frac{3 \times 6.02}{6.02} - 1 = 3 - 1 = 2$
