How do you find the dividend with a divisor 7?

Answer 1

If there is no remainder, you can use the relation:dividend = divisor x quotient

If you ONLY know the divisor, you don't have enough information; though you can make up any number for the quotient, and multiply them together to get the dividend.

Answer 2

You cannot. The dividend can be any number: positive, zero or negative, rational or irrational.

Answer 3

By multiplying the quotient by 7.
