How do you divide fractions???

Cross multiply:

For example, 4/5 divided by 6/7 would be 28/30 or 14/15.

3/4 divided by 2/3 would be 9/8 or 1 and 1/8

Actually, the word cross multiply is a misnomer. What is being done is multiplying by the reciprocal

for instance 4/5 divide by 6/7 is the same as 4/5 multiplied by 7/6

3/4 divided by 2/3 is the same as 3/4 multiplied by 3/2

Both 14/15 and 9/8 are correct for the examples given; however, I don't call that cross multiplying.To divide fractions, invert the deonimator and multiply.
(4/5)/(6/7) = (4/5)*(7/6)=28/30=14/15

(3/4)/(2/3) = (3/4)*(3/2)= 9/8.
