Answer 1

Answer:

please mark me brainlist plzzzzzzzzzzzzzz

Step-by-step explanation:

Let the number is x. This implies x can be expressed as x = 45y+30 where y is some natural number.

So, dividing x by 5 is same as

x/5 = (45y+30)/5 = 45y/5 + 30/5 = 9y + 6 which has to be again a natural number. Hence, the remainder is 0 or we can say that 5 is a perfect divider of x.
