Question

Determine whether the greatest and the smallest numbers formed by the digits 3, 0, 5, 2, 7 are divisible by 4 and 5 or not

Answer 1

Answer:

The greatest number formed by the digits 3, 0, 5, 2, 7 are divisible by both 4 and 5.

But the smallest numbers formed by the digits 3, 0, 5, 2, 7 are not divisible by 4 and 5.

Step-by-step explanation:

So in order to find if greatest number formed by the digits 3, 0, 5, 2, 7 are divisible by 4 and 5, we have to use the divisibility rule of 4 and 5

A number is divisible by 4 if the number formed by the last two digits in the given number divisible by 4 then the original number is divisible by 4.

A number is divisible by 5 if the last number is either 0 or 5, then the entire number is divisible by 5

Now the greatest number formed by the digits 3, 0, 5, 2, 7 is 75320 which is divisible by both 4 and 5

But smallest number formed is 20357 which is not divisible by 4 and 5
