Oh, what a lovely little math puzzle we have here! Let's see, to find the 4 numbers that multiply together to make 56, we can start by thinking about factors of 56. How about 1, 2, 4, and 14? When you multiply these numbers together, you get 56. Isn't that just delightful? Remember, there are many ways to approach a problem, and it's all about enjoying the process of discovery.
14, 20 or 5, 56 or 10, 28
7 * 8 = 56 1 * 56 = 56
More than that. You need to multiply the whole number, the farctions AND cross multiply the whole numbers and the fractions. Then add together all the answers. Thus, 23/4 * 56/7 = 2*5 + (3/4*6/7) + 2*6/7 + 3/4*5 Actually, it is far simpler to convert the mixed fractions to improper (top heavy) fractions, and then multiply the numerators together to give the numerator of the answer and multiply the denominators together to give the denominators of the answer.
1 x 56, 2 x 28, 4 x 14, 7 x 8
7*8 = 56
