The double of the number you multiplied to two
to get the answer of 28 there are two ways there is 2 times 14 there is also 7 times 4 those are the wo ways to get 28.
Let's say that you were multiplying 10 by 2/5 , you would turn the 10 into 10/1 which is still equal to 10 then you multiply 10/1 and 2/5 by multiplying the numerators (the top numbers) and the denominators (the bottom numbers) 10*2/1*5 = 20/5 = 4
