Really basic question.. how on a calculator can I find say 5/7 of a number? Im trying to figure out the following equation. "If 3/7 of n is 42, what is 5/7 of n?"

3/7 = 42 so 1/7 must be 42 divide 3 = 14 so 5/7 must 5 x 14 = 70
If anything, I think the calculator would be a hindrance here. It's easier to set up on paper , and less chances to make mistakes. The answer is 70, and n=98.
