Answer:

2 must be added

Step-by-step explanation:

divisibility rule of 5 is that any number ending with 0 or 5 is divisible by 5 so if we add 2 to 128 making it 130 thus it will become divisible by 5

Step-by-step explanation:

The smallest number to be added to 128, so as to make it divisible by 5 can be 2 or 7 .

However the smallest number is 2 .

We have taken 2 as the smallest number because the test of divisibility of 5 states that any number whose ones place is either 0 or 5 then the whole number is divisible by 5 .

Therefore nearest number that can make that is divisible by 5 is 130

Then

130 -128=2

therefore the smallest number to be added will be 2
