Question

вычеслите -3 3/4:1 1/2, (-4 2/3):2/9, (-6 1/4):(-5/8)

Answer 1

$- 3 \frac{3}{4} \div 1\frac{1}{2} = - \frac{15 \times 2}{4 \times 3} = - \frac{5}{2} = - 2.5$

$- 4 \frac{2}{3} \div \frac{2}{9} = - \frac{14 \times 9}{3 \times 2} = - 21$

$- 6 \frac{1}{4} \div ( - \frac{5}{8} ) = \frac{25 \times 8}{4 \times 5} = 20$
