Question

1) 14 - 15 1/₈ ÷ 2 1/₅ =
2) 95/₁₂ * 18/₅ =
3) 2) ÷1) =

Answer 1

$7\frac{1}{8};$  $28\frac{1}{2};$  $4;$

Пошаговое объяснение:

$1) 14-\frac{15*8+1}{8}:\frac{11}{5}=14-\frac{80+40+1}{8}*\frac{5}{11}=14-\frac{121*5}{8*11}=14-\frac{55}{8}=14-6\frac{7}{8}=7\frac{1}{8};$

$2) \frac{95}{12}*\frac{18}{5}=\frac{19*5*6*3}{6*2*5}=\frac{19*3}{2}=\frac{30+27}{2}=\frac{57}{2}=28\frac{1}{2};$

$3) \frac{57}{2}:7\frac{1}{8}=\frac{57}{2}:\frac{57}{8}=\frac{57}{2}*\frac{8}{57}=\frac{57*4*2}{2*57}=4;$
