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.

What is 981235 divisible by?
To determine what 981235 is divisible by, we can check for divisibility by common factors. It is divisible by 1, 5 (since it ends in 5), and 7 (981235 ÷ 7 = 140176.42857, not an integer). For a complete list, you would need to check divisibility by other numbers, but it is not divisible by 2, 3, or 4 since it does not meet their criteria.
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?
You can determine if a number is divisible by 7 by using the following method: E.g. 161 - Double the last digit (2 x 1 = 2) Subtract 2 from the number formed by the the remaining digits in this case, 16 -2 = 14 If the result is divisible by 7 (14 /7 =2); then the original number is divisible by 7. 161 / 7 = 23
