HOW TO DO THE BACKWARDS C

How to multiply a mixed number fraction. First you're going to do the backwards C and there's a little song to remember it when we do the backwards C when we do the backwards C the denominator stays the same the denominator stays the same then we multiply and add then we multiply and add and get a new numerator and get a new numerator. So we're going to do exactly that so you're going to get your fractions let's say ours is 1 and 3/4 * 2 and 4/5so we're going to do the backwards C to both of them then you should get 7/4 and 14/5 then you're going to multiply both of those what you'll get 98/20 so then you're going to convert that and get 4 and 9/20 and that's how you do the backwards C
