Question

(-3/4):1 1/2;5:(-5/8);-3 3/4:1 1/2;(-6 1/4):(-5/8)​

Answer 1

Ответ:

$- \frac{3}{4} \div 1 \frac{1}{2} = - \frac{3}{4} \times \frac{2}{3} = - \frac{6}{12} = - \frac{1}{2} \\ \\ 5 \div ( - \frac{5}{8} ) = 5 \times ( - \frac{8}{5} ) = - \frac{40}{5} = - 8 \\ \\ - 3 \frac{3}{4} \div 1 \frac{1}{2} = - \frac{15}{4} \times \frac{2}{3} = - \frac{30}{12} = - 2 \frac{6}{12} = - 2 \frac{1}{2} \\ \\ - 6 \frac{1}{4} \div ( - \frac{5}{8} ) = - \frac{25}{4} \times ( - \frac{8}{5} ) = \frac{200}{20} = 10$

Answer 2

Ответ:

1)-1/2

2)-8

3)-2,5

4)10

Пошаговое объяснение:

1)(-3/4):1 1/2=(-3/4):3/2=(-3/4)×2/3=-6/12=-1/2

2)5:(-5/8)=5/1×(-8/5)=-40/5=-8

3)(-3 3/4):1 1/2=(-15/4):3/2=(-15/4)×2/3=-30/12=-5/2=-2,5

4)(-6 1/4):(-5/8)=(-25/4):(-5/8)=(-25/5)×(-8/5)=200/20=10
