Question

The product of two rational numbers is -26/15.If one of the numbers is 2/5,find the other number.

Answer 1

Let the other number be x.
X+ 2/5=-26/15
=>x=-26/15-2/5
=>x= - 32/15

Answer 2

let's take the other no as x :
2/5 x X = -26/15
X = -26/15 divided 2/5
X= -26/15 x 5/2
X= -13/5
-13/5 is the answer
