I'll do the first one. Then you can use it as a model to do the other two.
3/7 divided by 2/3
When we divide fractions, we change the division sign to a multiplication sign and invert the divisor.
(3/7) * (3/2) =
Multiply the numerators together. Multiply the denominators together.
(3/7) * (3/2) = 9/14
