Using the breaking apart method, what is the best way to multiply 8 by 7?

Asked by sadgirl

Answer (2)

if we multiply 8 and 7 we get the answer: 8 x 7 = 56 Now we are going to break apart the number in such a way that we still get the answer 56. we can split 8 into 2 equal parts 4 and 4, so 8 = 4+4 but 7 cannot break apart in equal part so, (4+4) x 7 = 56 we can also add 7, 8 times or add 8 7 times and still get the answer 56, 7+7+7+7+7+7+7+7=56 8+8+8+8+8+8+8 = 56

To multiply 8 by 7 using the breaking apart method, we can split 8 into 4 and 4, then multiply each part by 7 and add the results together. This gives us 56. We can also think of this multiplication as adding 7 together eight times or adding 8 together seven times, both leading to the same answer.
