Question

By what number should we multiply `(-8)/13` so that the product may be 24?

Answer 1

Let us assume the other number be y.

Given, product of two rational number = 24

One number = `(-8)/13`

Then,

⇒ `y xx (-8)/13 = 24`

⇒ `y = 24/((-8)/13)`

⇒ `y = 24/1 xx (-13)/8`

⇒ `y = 3/1 xx (-13)/1`

⇒ y = –39

So, the other number is –39.
