Question

Using the divisibility tests, determine weather the following numbers are divisible by 3, 4, and 9
220​

Answer 1

Answer:

It is only divisible by 4

Step-by-step explanation:

Let's check with 3

...for checking if it is divisible by 3

the sum of the digits of the number should be divisible by 3

So, 2+2+0 = 4

which is not divisible by 3

Let's check with 4

...for 4 the last two digits of the number should be divisible by 4 then, the whole number is divisible by 4

for 220 ,20/4 = 5 and completely divides

So this is divisible by 4

and for 9

It is like 3 , the sum of the digits should be divisible by 9

2+2+0= 4 which is again not divisible by 9
