okay we have a whole number with a fraction times a fraction when we have a whole number times a fraction we need to turn that into a fraction itself so we can do the operation and what we want to do is take that and do the Big C and that is the denominator which is 10 times the whole number which is 13 and then all that added 27 / that original denominator of 10 seems like a lot of work but that's what you do you take the Big C to make a fraction all itself and that would be 10 times 13 is a hundred and thirty and then we add seven more to it is 137 and then all over the original denominator which is 137 / 10 times one over nine 137 oops sorry about that need to erase that okay 137 / 10 times 1 over 9 so now that we have two fractions we can just multiply the tops for a new top and multiply the bottoms for a new bottom and we have our answer however if it asks for a proper fraction at
