What is the rule for multiplying 7s?
For each multiple add 7. For example 12*7= 84 therefore 13*7= 91 (84+7)
What is the divisibility rule for 4 7 8?
4- last two digits are a multiple of 4 7-take the last digit and subtract it from the rest of the number and if multiple of 7 (including 0) 8- last three digits are multiple of 8
What is the rule for dividing by 7?
I assume you mean "divisibility rule". Separate the last three digits, and subtract it from the remaining digits. For example: 45003: separate 45 and 003, and subtract 45 - 3 = 42. Since 42 is a multiple of 7, the original number is a multiple of seven. Note that this rule works for 7, 11, and 13. The reason it works is related to the fact that 1001 = 7 x 11 x 13.
