(a) Write a pair of negative integers whose difference gives 8. (b) Write a negative integer and a positive integer whose sum is –5. (c) Write a negative integer and a positive integer whose difference is –3. NCERT Class 7th Mathematics Chapter 1 Integers

Answer 1

Hey there!

( a) Let the pair of integers be -8 , -16

Their difference = -8 - ( -16 )

= -8 + 16

= 8

Required pair is ( -8 , -16 )

b) Let the number be -15 , 10 .

Their sum = -15 + 10 = -5 .

The required pair ( -15 , 10 )

c) This is not possible.

Difference between a positive integer and negative integer is never a negative integer.
