Which is a good comparison of the estimated sum and the actual sum of 7 9/12 + 2 11/12?
Answers
2 11/12 = 2.917
So we can round both of these up.
7.75 rounds to 8
2.917 rounds to 3
8 + 3 = 11
So the estimated sum is 11.
7 9/12 + 2 11/12 = 10 2/3
So the actual sum is 10 2/3.
The estimated sum is a pretty good estimate to the original number.
((12*7)+9)/12+((12*2)+11)/12
93/12+35/12
128/12 divide by 2
(128/2)/(12/2)
64/6 divide by 2
(64/2)/(6/2)
32/3
10 2/3

The required 100 to the 6th power is equal to 1,000,000,000,000,000,000.
To calculate 100 to the 6th power, follow these steps:
Step 1: Start with the base, which is 100.
Step 2: Multiply the base by itself (100 * 100 = 10,000) to get the result of the base raised to the power of 2.
Step 3: Multiply the result from the previous step (10,000) by the base (100,000,000) to get the result of the base raised to the power of 3.
Step 4: Repeat this process until you reach the desired power of 6. Multiply the result from the previous step (100,000,000) by the base (10,000,000,000,000).
Step 5: Continuing this pattern, multiply the result from the previous step (10,000,000,000,000) by the base (1,000,000,000,000,000,000) to get the result of the base raised to the power of 6.
Step 6: Simplify the final result.
So, 100 to the 6th power is equal to 1,000,000,000,000,000,000.
