0
To find out whether a no. is divisible by 7, we must: a) separate the units place: eg. 84 = 8 4 b) then double the no. in units place 4 x 2 = 8 c) subtract it from the no. formed by the remaining digits 8- 8 = 0 Then if the obtained no. is divisible by 7 (0= 7x0) , then the original no. is also divisible. ( 12 x 7 = 84 )

Is 87 divisible by 7?
No, 87 is not divisible by 7. To determine if a number is divisible by 7, you can use the rule that states a number is divisible by 7 if the difference between twice the digit in the ones place and the number formed by the other digits is either 0 or a multiple of 7. In this case, the number formed by the other digits is 8, and twice the digit in the ones place is 14. The difference between 14 and 8 is 6, which is not a multiple of 7, so 87 is not divisible by 7.

Is 7960 a divisible by 3?
To determine if a number is divisible by 3, you need to add up its individual digits. In this case, 7 + 9 + 6 + 0 = 22. Since 22 is not divisible by 3 (it does not result in a whole number), 7960 is not divisible by 3.
What is the divisibility test for 7?
