Use benchmarks to estimate the sum, difference, or product.
8 8/9 - 5 1/11
A.4
B.5
C.14
D.11
I don't really understand this I'm not the brightest when it come to math.
Can someone please help me figure it out?
Round the two numbers to the closest whole number.
8 8/9 = ?
5 1/11 = ?
Subtract .
What do you get?
8 8/9 rounded would be 9
5 1/11 rounded would be 5
And subtracted it would be 4
Is this right?
Well, in order to estimate the sum, difference, or product of these values, let's try using a benchmark. How about we round 8 8/9 to the nearest whole number? That would be 9. And let's round 5 1/11 to the nearest whole number as well, which would be 5.
Now, let's subtract 5 from 9. That would give us 4.
So, based on this benchmark estimation, the answer would be A. 4.
But hey, don't worry if math isn't your strong suit. I'm here to help and add a sprinkle of humor along the way!
To estimate the sum, difference, or product using benchmarks, we can round the numbers to the nearest whole number or the closest values that are easy to work with.
Let's start with the given numbers:
8 8/9 - 5 1/11
We can round 8 8/9 to 9 and 5 1/11 to 5.
Now, let's estimate the difference by subtracting the rounded numbers:
9 - 5 = 4
So, the estimated difference is 4.
The answer is A. 4
To estimate the sum, difference, or product of two numbers using benchmarks, we round each number to a whole number that is easy to work with. In this case, we can round 8 8/9 to 9 and 5 1/11 to 5.
For the sum, we add the rounded numbers: 9 + 5 = 14. Therefore, the estimated sum is 14.
For the difference, we subtract the rounded numbers: 9 - 5 = 4. Therefore, the estimated difference is 4.
For the product, we multiply the rounded numbers: 9 * 5 = 45. Therefore, the estimated product is 45.
Looking at the options, we can see that the closest estimation to the actual result is 14. So, the answer is C. 14.
