If you want to divide a%2Fb by c%2Fd, then you're going to multiply the first fraction by the reciprocal of the second fraction. So you're going to multiply a%2Fb by d%2Fc.



So in your case, you have 2 fractions: 3pi%2F2 and 3%2F1 (note: 3=3%2F1)


So to divide them, simply flip the second fraction to get 1%2F3 and multiply that by the first fraction to get


%283pi%2F2%29%2A%281%2F3%29=%283pi%2A1%29%2F%282%2A3%29+=+%283pi%29%2F%286%29+=+pi%2F2


Note: the 3's basically cancel out and go away


So %283pi%2F2%29%2A%281%2F3%29=+pi%2F2


This means that


%283pi%2F2%29%2F%283%2F1%29+=+pi%2F2


which means that


%283pi%2F2%29%2F%283%29+=+pi%2F2
