Question

Помогите пожалуйста срочно нужна помощь

Answer 1

1) 1/2x = 1/8

x = 1/8 : 1/2 = 1/8 × 2

x = 2/8 = 1/4

2) 1/7x = 1/14

x = 1/14 : 1/7 = 1/14 × 7

x = 7/14 = 1/2

3) 4/3x = 14/12

x = 14/12 : 4/3 = 14/12 × 3/4 = 7/6 × 3/4

x = 7×3/6×4 = 21/24 = 7/8

4) 4/7x = 2/28

x = 2/28 : 4/7 = 2/28 × 7/4 = 1/14 × 7/4

x = 1×7/14×4 = 7/56 = 1/8

5) 10x = 100

x = 100/10

x = 10

6) 2x = 10

x = 10/2

x = 5
