Best Answer

You look at the fractions sideways. Lets say that you had 3/4 and 2/3 and you were multiplying them. Put them on paper. Now you can see that 4 and 2 are compatible. What you do is:

Cross out the four and put a 2. This means 2 goes into 4 twice.

Then cross out the 2 and put a 1. This means that 2 goes into 2 once. Now you just multiply.

Hope that answered your question!
