Question

Решите уравнения :
7,8/b = 9,1/9,8
32/120 = 36/k
3,3/4,5 = 5,5/g
1,6/6 = 2/x
y/30 = 7/105
a/2 = 5,6/8

Answer 1

7.8*9.8=9.1b   76.44=9.1b b=8.4
32k=4320   k=135
3.3g=24.75    g=7.5
12=1.6x  x=7.5
105y=210   y=2

Answer 2

7,8/b = 9,1/9,8 b=8'4
32/120 = 36/k k=135
3,3/4,5 = 5,5/g g=7,5
1,6/6 = 2/x x=7.5
y/30 = 7/105 y=1,4
a/2 = 5,6/8 a=1,4
