-7 x -4 - 8 = -20
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).
8 x 7 + (4/4) = 57
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).
To find how many times larger (4 \times 10^{12}) is than (8 \times 10^{7}), divide the two numbers: [ \frac{4 \times 10^{12}}{8 \times 10^{7}} = \frac{4}{8} \times \frac{10^{12}}{10^{7}} = 0.5 \times 10^{5} = 5 \times 10^{4}. ] Thus, (4 \times 10^{12}) is (50,000) times larger than (8 \times 10^{7}).
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.
Doubling 4 is 8. 8 times 7 is 56.
How about: 4 times (7-8/8) = 24
7 times with a remainder of 4 or 7.5 times
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).

2 8/7 divided by 4/7 is the same as 8/7 times 7/4... The 7s then cancel out and you get 8/4 which is 2

7/8 x 4/5 = 28/40 or 7/10
