Пошаговое объяснение:

1) 5*3 = 15

2x*6 = 12x

12x = 15 (/12)

x = 5/4 = 1 1/4 = 1,25

2) 4*45 = 180

8x*9 = 72x

72x = 180

x = 5/2 = 2 1/2 = 2,5

3) 2*12 = 24

5x*3 = 15x

15x = 24

x = 8/5 = 1 3/5 = 1,6

4) 6*21 = 126

10x*7 = 70x

70x = 126

x = 9/5 = 1 1/4 = 1.8

5) 8*27 = 216

4x*9 = 36x

36x = 216

x = 6

6) 27*16 = 432

5x*9 = 45x

45x = 432

x = 48/5 = 9 3/5 = 9,6
