Question

How many whole numbers are there between 56 And 89?​

Answer 1

89-56=33 is correct answer

Answer 2

Hey♥️

The no. of whole numbers between 89 and 56 =

(89 - 56) - 1 = 32

I subtracted 1 from 33 because, the question was to find whole number between the given numbers.

For Eg:-

Find the whole numbers between 1 and 4

If we do 4 - 1 = 3,

It would be incorrect since there are only 2 whole numbers between 1 and 4 , they are 2 and 3; because, 1 and 4 will be excluded.

So, if we subtract 1 from 3 which will be equal to 2, we will obtain the correct answer.

Therefore, the no. of whole numbers between two numbers a and b

Therefore, the no. of whole numbers between two numbers a and b will be (a - b) -1.
