You can use 4x7 to find 8x7 because 4 x 2 is 8, and you are simply doubling one of the numbers you are multiplying, (4 to 8) and so multiply your answer from 4x7 by 2 to get the answer to 8x7. 4x7 is 28 and 8x7 is 56, and 28 x 2 is 56.

How can you use 4s facts to find 7x8 give the product in your explanation?

You can use the fact that 4 times 2 equals 8 to help find 7 times 8. Since 7 times 4 equals 28, you can double that product to find 7 times 8. So, 7 times 8 is 28 doubled, which equals 56. Therefore, 7 times 8 is 56.


How can you use 4x7 to find8x7 find the product?

To find (8 \times 7) using (4 \times 7), you can first calculate (4 \times 7), which equals (28). Since (8) is double (4), you can simply double the result: (28 \times 2 = 56). Therefore, (8 \times 7 = 56).

What multiplicalion fact can you double to find 4times7?

To find 4 times 7, you can double the multiplication fact of 2 times 7. Since 2 times 7 equals 14, doubling that gives you 4 times 7, which also equals 28. Thus, 4 times 7 can be derived from doubling 2 times 7.


How can use 4x8 to find 7x8?

To find (7 \times 8) using (4 \times 8), you can break down (7) into (4 + 3). First, calculate (4 \times 8), which equals (32). Then, calculate (3 \times 8) (which can also be done as (4 \times 8 - 4 \times 8 + 3 \times 8)), resulting in (24). Finally, add the two results: (32 + 24 = 56), so (7 \times 8 = 56).
