Question

помогите пожалуйста​

Answer 1

первое:

1)4 + 1/2 = 4 1/2 = 9/2

2)3 ÷ 9/2 = 3 × 2/9 = 2/3

3)5 - 2/3 = 15/3 - 2/3 = 13/3 = 4 1/3

второе:

1)1 - 1/3 = 3/3 - 1/3 = 2/3

2)4 ÷ 2/3 = 4 × 3/2 = 6

3)3 + 6 = 9

третье:

1)3 - 1/2 = 6/2 - 1/2 = 5/2

2)5 ÷ 5/2 = 5 × 2/5 = 2

3)6 - 2 = 4

четвёртое:

1)6 + 2/3 = 18/3 + 2/3 = 20/3

2)4 ÷ 20/3 = 4 × 3/20 = 3/5

3)2/5 + 3/5 = 5/5 = 1
