You should always give an example: So, if you wanted to multiply 2/3 X 4/5=You multiply the top numbers together like this: 2 X 4=8, that is your top number. Now, do the same with bottom numbers,
like this: 3 X 5 =15, so you put the first number 8 on top and the second number 15 on the bottom like this: 8/15. And that is your answer.
