3/5+3/17 use benchmarks to estimate the sum.
A. 2
B. 1/2
C. 1
D. 0
I think the answer is D, but I could be wrong.
Answer:
3/5 is a almost one
3/17 is small
so the sum is about 1
3/5+3/17 is close to 3/5 +3/15
= 3/5 + 1/5 = 4/5 which is almost 5/5 or 1

To estimate the sum of 3/5 and 3/17 using benchmarks, we can round the fractions to the nearest whole numbers:
For 3/5, we can round it to 1 because it is closer to 1 than 0.
For 3/17, we can round it to 0 because it is closer to 0 than 1.
Now, we can add the rounded fractions: 1 + 0 = 1
Therefore, the estimated sum of 3/5 and 3/17 is 1.
The correct answer is C. 1.
