Question

the product of two rational numbers is minus 16 by 9 if one of the numbers is minus 4 by 3 find the other number

Answer 1

let the other rational number be x

-4/3(x) =(-16/9)

x = -16/9/-4/3

x = 4/3

simple

Answer 2

Concept

If p and q are integers and q is not equal to 0, then the number is in the form of p/q and is said to be rational. Among the rational number examples are 1/3, 2/4, 1/5, 9/3, and so forth.

Given

Product of two rational numbers = ₋16/9

one number = ₋4/3

Find

we are asked to to determine the other number in the given product of two rational numbers.

Solution

let the other rational number be x.

Therefore product of two rational numbers is ₋16/9

x × ₋4/3 = ₋16/9

x =  ₋16/9 ÷  ₋4/3

x =  16/9 × 3/4

x = 4/3

Therefore we get the value of the other rational number as 4/3.
