Question

write five pairs of integers (a,b) such that a÷b=-5 where one such pair is (-25,5) because-25÷5=-5

Answer 1

(-10,2) , (-15,3) , (-20,4) , (-60,12) , (-65,13) is the right answer.

Answer 2

Concept

Division and multiplication are opposites of each other.

Given

a/b = -5

Find

we are asked to five pairs of integers (a, b) such that a/b = -5 where one such pair is (-25,5)

Solution

We know that

a/b = -5

⇒ a = -5b

There can be many such pairs of integers satisfying the equation but we need to find only 5 of them. Therefore, we take a few values of b and find a few pairs.

if b = 1,  a = -5

if b= 2, a = -10

if b= 3, a = -15

if b= 4, a = -20

if b= 5, a = -25

Thus, five pairs of integers (a, b) such that a/b=-5  where one such pair is (-25,5) are- (-5,1) (-10,2) (-15,3) (-20,4)
