Question

посогите срочно решите уравнение
7целых1/3:1целую5/6=х:5/8
2,8:0,14=5,6:x

Answer 1

1)
$7frac{1}{3}:1frac{5}{6}=x:frac{5}{8};\ frac{22}{3}cdotfrac{6}{11}=x:frac{5}{8};\ x=4cdotfrac{5}{8};\ x=frac{5}{2}=2frac{1}{2}.$

2)
$2,8:0,14=5,6:x;\ x=frac{0,14cdot5,6}{2,8}=0,14cdot2=0,28.$

Answer 2

1) (7 1/3):(1 5/6)=х/(5/8)
((7*3+1)/3):((1*6+5)/6=х*(8/5)
(22/3):(11/6)=8*х/5
(22/3)*(6/11)=8*х/5
(22*6)/(3*11)=8*х/5
4=8*х/5
х=4*5/8=20/8=5/2=2 1/2
2) 2,8:0,14=5,6:х
20=5,6:х
х=5,6/20=0,28
