Question

А) x/4=20/10ә) x/0,6=7,8/3,6б) 120:9=z:18​

Answer 1

х/4=20/10

20*х=10*4

20х=40

х=40:20

х=2

х/0,6=7,8/3,6

х*3,6=0,6*7,8

3,6х=4,68

Х=4,68:3,6

Х=1,3

120:9=z:18

120/9=z/18

120*18=9*z

9z=2 160

z=2 160:9

z=240

Answer 2

To solve these equations, you can follow these steps:

A) x/4 = 20/10

1. Multiply both sides of the equation by 4 to isolate x: (x/4) * 4 = (20/10) * 4

2. Simplify: x = 8

Ә) x/0.6 = 7.8/3.6

1. Multiply both sides of the equation by 0.6 to isolate x: (x/0.6) * 0.6 = (7.8/3.6) * 0.6

2. Simplify: x = (7.8/3.6) * 0.6 x = 1.3

Б) 120/9 = z/18

1. Multiply both sides of the equation by 18 to isolate z: (120/9) * 18 = (z/18) * 18

2. Simplify: z = (120/9) * 18 z = 240

So, the solutions are: A) x = 8 Ә) x = 1.3 Б) z = 240
