3/4 * x = 72
x=72:3/4=72*4/3=96
a) 150 : 2/3 =225 lei
b) 415 :2/3 =622,5 m
c) 1230 :2/3=1845 cm
x=72:3/4=72*4/3=96

1. 3 /4 · x = 72 x = 72 · 4 :3 = 96
2 . 2 /3 · x = 150 lei x = 150 · 3:2 = 225 lei
2 /3 · x = 415 m x = 415 · 3 :2 m = 622,5 m
2 /3 · x = 1230cm x = 1230 · 3 :2 cm = 1845 cm
2 . 2 /3 · x = 150 lei x = 150 · 3:2 = 225 lei
2 /3 · x = 415 m x = 415 · 3 :2 m = 622,5 m
2 /3 · x = 1230cm x = 1230 · 3 :2 cm = 1845 cm
