How do i divide and simplify?

5/7 divided by 35/3
Answered by Ms. Sue
5/7 divided by 35/3.

When dividing fractions, you need to invert the second fraction (turn it upside down) and then multiply.

5/7 divided by 35/3 = 5/7 * 3/35

5/7 * 3/35 = 15/245 = 3/49

How did you get 3/49 from 15/245?
Answered by Ms. Sue
I divided by the largest number that goes into both 15 and 245. Since both numbers end in 5, I knew that both are divisible by 5.
Answered by Bryan
Okay so when your dividing you flip the second fraction and multiply.

what do you do when multiplying fractions?

4/5 times 6/7
Answered by Ms. Sue
You multiply the numerators and denominators.

4/5 * 6/7 = 24/35
Answered by Bryan
the denominators dosen't have to be the same?
Answered by Ms. Sue
No.

Denominators need to be the same when you're adding and subtracting fractions.

They do not need to be the same when you're multiplying or dividing fractions.
