Question

4 3/4: 7 3/5=
8,4 : (-0,08)=

Answer 1

$4 \frac{3}{4} \div 7 \frac{3}{5} = \frac{19}{4} \times \frac{5}{38} = \frac{1}{4} \times \frac{5}{2} = \frac{5}{8}$

$8.4 \div ( - 0.08) = - (8.4 \div 0.08) = - 105$

Answer 2

Ответ:

4 3/4:7 3/5=(4×4+3)/4:(7×5+3)/5=19/4:38/5=19/4×5/38=1/4×5/2=(1×5)/(4×2)=5/8

8,4:(-0,08)= -(8,4÷0,08)=-(105)=-105
