Answer 1

Answer:

What is the smallest number that should be added to 100 to make the sum exactly divisable by 45?

Let's know some math now.

Count in 45s

45*1=45.

Let's subtract 100 from 45, we will get -55. This is not possible

45*2=90

Let's subtract 100 from 90 we get -10. This is also not possible

45*3=135

Now the number above 100 is 135. Subtracting 100 from 135 we get 35.

35 is the answer.
