**Ms. Sue**, Thursday, August 18, 2011 at 9:34pmI'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.

Multiply the numerators together. Multiply the denominators together.

(3/7) * (3/2) = 9/14
