Answer 2

The other number is 7/10

Given,

p × q = -7

p = -10

To Find,

The value of q

Solution,

A rational number is a number that can be written in the form p/q where p and q are integers and q≠0

We have been given that the product of two rational numbers is -7

Let the rational numbers be p and q

Therefore, p × q = -7

We have also been given that one of the rational numbers, say p, is -10

⇒ -10q = -7

⇒ q = (-7)/(-10)

⇒ q = 7/10, which is a rational number
