Question

using divisibility test, determine whether 86020 is divisible by 2,3,5,9 and 4.​

Answer 1

Step-by-step explanation:

A number is divisible by 2 if the last number is a even number. As the last number of 86020 is an even number it is divisible by 2.

A number is divisible by 3 if the sum of number is divisible by 3. 8+0+6+0+2=16 as 16 is not divisible by 3 the number is also not divisible by 3.

A number is divisible by 5 when the last digit is 0 Or 5. As here the last digit is zero it is divisible.

A number is divisible by 4 if the sum is divisible by 4 here the sum is 16 therefore it is divisible by 4.

Answer 2

Answer:

divisibility by 2

A number is divisible by 2 if the last number is an even number. As the last number of 86020 is an even number it is divisible by 2.

divisibility by 3

A number is divisible by 3 if the sum of the number is divisible by 3. 8+0+6+0+2=16 as 16 is not divisible by 3 the number is also not divisible by 3.

divisibility by 5

A number is divisible by 5 when the last digit is 0 Or 5. As here the last digit is zero it is divisible.

divisibility by 4

A number is divisible by 4 if the sum is divisible by 4 here the sum is 16 therefore it is divisible by 4.
