Question

Using divisibility tests determine whether 218750 is divisible by 6, by 8 and by
9.

Answer 1

Answer:

This no. is not divisble by 6 ,8 and 9

The reasons for the following：-

•number is divisible by 9, if the sum is a multiple of 9 or if the sum of its digits is divisible by 9.

•number is divisible by 8 if the numbers formed by the last three digits is divisible by 8.

•number is divisible by 6 if it is divisible by 2 and 3 both.

Answer 2

Answer:

Step-by-step explanation:

Divisibility rule of 2=Last number 0,2,4,6,8

Divisibility rule of 4=Last 2 numbers must be divisible by 4

Divisibility rule of 3=Sum of digits must be divided by 3

Divisibility rule of 6=Number should be divisible by 2 and 3

Divisibility rule of 8=Last three digits must be divisible by 8

Divisibility rule of 9=Sum of digits must be divisible by 9

Now let's check

218750

First of 6=Not divisible by 3 (2+1+8+7+5+0=23 which is not divisible by 3)

Second of 8=Last three digits 750/8=93.75(not a whole number) hence not divisible

Third of 9=Sum of digits(2+1+8+7+5+0=23 which is not divisible by 9) hence not divisible

Answer:Hence,218750 is not divisible by 6,8 and 9.
