1 1/3 * 3 = 4/3 * 3
I think it's D, am I wrong?

Before you can do D, you need at least A
Answered by Reiny
Even after doing A, you would not "cross-multiply" numerators and denominators
when multiplying two fractions.

e.g. (4/7)(3/8) = 12/56
= 3/14 , I multiplied the numerators and the denominators, then reduced to lowest terms

Once you become more comfortable with it, you can "cancel" common factors
in the numerators and the denominators.
I see now, thanks Reiny and oobleck!
