How to Multiply Mixed Numbers

So, say you have the problem 2 and 3/8 x 5 and 3/5.

 First, you think what equals one whole with the denominator of 8.

 We know that it is 8/8 but, we have 2 so what is 8/8 + 8/8 + 3/8= 19/8.

Now, we do the same thing to 5 and 3/5. What equals 1 whole with the denominator of 5. So, our equation is 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 3/5= 28/5.

 Then, we just straight out multiply the numerators by each other and the denominators by each other. So, the equation now is 19/8 x 28/5= 532/40.

 Finally, we have to simplify so we have to think how many times does 40 go into 532. That is 13 and 12/532= 6/266= 3/133. So, you answer is 13 and 3/133.
