3,7:11,1=х:7/9 ПРОПОРЦИЕЙ

Question

3,7:11,1=х:7/9 ПРОПОРЦИЕЙ

Answer 1

11,1х=3,7×7/9

111х/10=(37×7)/90

111х×90=37×7×10

х=(37×7×10)/(90×111)

x=7/(9×3)

x=7/27

Comments

х = 3,7 * 7/9 : 11,1х = 37/10 * 7/9 : 111/10х = 37/10 * 7/9 * 10/111х = 7/27

Answer 2

3,7*7/9=11,1х
37/10*7/9=11,1х
259/90=11,1х
11.1х=259/90
х=7/27
