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