9 1/3 x 3 3/8
do I change them to improper fractions?
Yes, that makes it easier. You would then
multiply the two numerators to get the new numerator,
and multiply the two denominators to get the new denominator.
After that, you can reduce the fraction, and make it into
a mixed number if necessary.
9 1/3 x 3 3/8
28/3 x 27/8
(28 x 27)/(3 * 8)
Actually, you can start reducing at this point.
(28 x 27)/(3 * 8) ..... 28/8 = 7/2 ...... 27/3 = 9/1
(7 * 9)/(2 * 1)
63/2
31 1/2
