How much is 2/5 divided by 1/7?

(2/5) / (1/7)

You can make this easier to solve by switching the sign to multiplication and flipping the second fraction.

(2/5) * (7/1)

14/5

The answer is 14/5 or if you want it simplified, 2.8.

14/5 ... change the problem to 2/5 * 7/1 because the rule states you keep the first fraction then flip the sign to multiplication and flip the 2nd fraction. 2*7 is 14 and 5*1 is 5 so the answer is 14 in the numerator and 5 in the demoninator ... 14/5
