How can you use 4x7 to find 8x7?
Solve the 4x7 and multiply the product by 2. And you will get the same answer as 8x7. (56)
8x7 = (4+4)x7 = 4x7 + 4x7 = 2x4x7
To use 4x7 to find 8x7, you can make use of the distributive property of multiplication. Here are the steps:
1. Multiply 4x7: 4x7 = 28.
2. Divide the product of 8x7 (which is what we want to find) by 4: (8x7) / 4 = (7+7) / 4.
3. Use the distributive property: (7+7) / 4 = (4/4)x7 + (4/4)x7.
4. Simplify: (4/4)x7 + (4/4)x7 = 1x7 + 1x7 = 7 + 7 = 14.
Therefore, 8x7 equals 14.
To use 4x7 to find 8x7, you can follow the concept of multiplication by doubling. Here is how you can do it step by step:
1. Start with 4x7. Multiply 4 by 7 to get the product: 4x7 = 28.
2. Double the result from step 1. Since 28 doubled is 56, we now have 56.
3. Therefore, 8x7 is equal to 56.
So, by doubling the product of 4x7, which is 28, we get the answer of 8x7 equals 56.
