Hi, we're multiplying fractions in math now, and I'm having some trouble. Can you explain how to do this?
user
Sure, let's try some problems together.
assistant
Okay, well the problem I have to do first is 1/2 x 3/4. How do I get the answer?
user
First, we want to make the denominators (which are 3/4 and 2/4) match up, so that it's easier to multiply. We do that by switching the 3/4 and the 2/4, so that we have 1/4 x 2/4, or 2/8 x 2/4, and then we can multiply the top two numbers together. Do you know what we mean by “matching the denominators”?
assistant
Not, really, I'm confused, are you telling me that 1/2 x 3/4 is the same as 2/8 x 2/4?
user
Not quite.   To better understand what’s going on, we can break the fractions apart, so that we get 1/2 = 1/2 x 1/2, and then we can write the answer as 1/4 x 2/8.  The key thing is that if we have a fraction, and we want to multiply it with another fraction, we need to make sure the denominators are the same.

I'm sorry, let's start again. I'm trying to say that we don't want the numbers 2/4 and 3/4 next to each other in our problem. So we want to swap them around, so that we have 2/4 next to 2/8. The idea is that we're going to use the division, 1/2, in the numerator, which means that it will be the top number, and the answer we want is 1/2 times the bottom number, which is 2/8. Do you understand what I mean?
