Step-by-step explanation:

Given : by what rational number should +15 /56 be divided to get -5/7?

To find : by what rational number should +15 /56 be divided to get -5/7?

Solution :

Let x be multiplied then

x = − 1 5 / 5 6 = - 5 / 7

x = − 5 / 7  ÷ - 15 / 56

x = − 5 / 7 × 5 6 / − 1 5

x = − 2 8 0 / − 1 0 5

x =2 8 0 / 1 0 5

x =2 8 0 ÷ 3 5 / 1 0 5 ÷ 3 5

x = 8 / 3

∴ Required rational number

= 8 / 3
