Estimate the difference. Use the benchmarks 0,1/2 and 1.
23/40 - 11/30
a.1
b.1/2
c.0
d.1 1/2
pls help
What is 1/2 -0 ?
1/2? can you be more specific?
Joe, 1/2 means One Half, thought that was obvious T^T
And Bob Pursley, it's still 1/2, cause 1/2 - 0 doesn't do anything, so it's still 1/2
So is the answer 1/2?
To estimate the difference between 23/40 and 11/30 using the benchmarks 0, 1/2, and 1, we can compare the fractions to the benchmarks and then determine which option is the closest estimate.
First, let's compare 23/40 to the benchmarks:
- 23/40 is more than halfway between 1/2 and 1 (1/2 < 23/40 < 1).
Next, let's compare 11/30 to the benchmarks:
- 11/30 is more than halfway between 0 and 1/2 (0 < 11/30 < 1/2).
Based on these comparisons, we can see that 23/40 is closer to 1 than 11/30 is to 0.
Therefore, an estimate of the difference between 23/40 and 11/30 is 1. The answer is (a) 1.
