Question

If the product of any two rational numbers is 4 and one of them is 6/7, find the other?

A) 3/14
B) 14/3
C) 1
D) 2​

Answer 1

Answer:

14/3

Step-by-step explanation:

lets a/b be the rational we want to find.

So, given

a/b * 6/7 = 4

a/b = (4*7)/6

a/b = 28/6

a/b = 14/3

Check:

a/b * 6/7 = 4

LHS => 14/3 * 6/7 = 2 *2 = 4 = RHS
