Ответ:

2/5.

пошаговое обеснение:

1 1/5 : 1 = (2x) : 2/3

Первый способ решения:

1 1/5 : 1 = (2x) : 2/3

1 1/5 = (2x) : 2/3

2х = 2/3 • 1 1/5

2х = (2•6)/(3•5)

х = (2•6)/(3•5•2)

х = 2/5

Ответ: 2/5.

второй спосаб решения:

1 1/5 : 1 = (2x) : 2/3

1•2х = 1 1/5•2/3

2х = 6/5•2/3

х = 6/5•2/3 : 2/1

х = 6/5•2/3•1/2

х = (6•2•1)/(5•3•2)

х = 2/5

Ответ: 2/5.

Answer 2

1 + 1/5 + 1 = 2 + 1/5 To add these numbers, we first need to find a common denominator for the fractions. In this case, the common denominator is 5. So we rewrite 2 as 10/5: 10/5 + 1/5 + 1 = 11/5 So the final answer is 11/5 or 2.2.
