Question

Check the divisibility of a) 612 by 4 ( Give reason)

b) 3382 by 5 (Give reason)​

Answer 1

Answer:

Solution :

(a) 612 is divisible by 4

(b) 3382. is not divisible by 5

Step-by-step explanation:

(a)To check whether a number is divisible by 4, just divide the last two digits of the number by 4. If the result is a whole number, then the number is divisible by 4.

When we divide the last two digits (12) by 4 we get a whole number which is 3. So, 612 is divisible by 4

(b) The divisibility rule of 5 states that if the digit on the units place, that is, the last digit of a given number is 5 or 0, then such a number is divisible by 5.

Last digit of 3382 is not 5 or 0 so it's not divisible
