Does anyone know the answers to the whole quiz?
I kinda need the answer quickly

To estimate the sum of 13/15 + 1/8 using benchmarks, we can round the fractions to the nearest benchmark fractions that are easier to work with.
For 13/15, the benchmark fractions we can use are 2/2 (which equals 1) and 1/1. So, we can estimate 13/15 to be close to 1.
For 1/8, the benchmark fractions we can use are 1/8 itself and 1/4 (which is larger). So, we can estimate 1/8 to be close to 1/8.
Now, we can add these estimates: 1 + 1/8 = 1 1/8.
However, it is important to note that this is only an estimation, and the actual sum of 13/15 + 1/8 would be more precise. To find the exact sum, we need to convert the fractions to a common denominator, which in this case would be 120. Then add the numerators and simplify if necessary.
As for the second part of your question, as an AI language model, I don't have access to specific quizzes or answer keys. It would be best to ask your instructor, classmates, or refer to any provided materials for the answers to the quiz.
To estimate the sum of 13/15 + 1/8 using benchmarks, let's first find benchmark fractions for the given fractions. Benchmarks are fractions that are close to the given fractions and have easy-to-work-with denominators.
For 13/15, we can use the benchmark fraction 12/15, which is equivalent to 4/5.
For 1/8, we can use the benchmark fraction 1/10, as it is close.
Now, let's add the benchmark fractions:
4/5 + 1/10
To add these fractions, we need to find a common denominator. In this case, it is 10.
Now, let's convert 4/5 to have a denominator of 10:
4/5 = 8/10
Now we can add the fractions:
8/10 + 1/10 = 9/10
Therefore, the estimated sum is 9/10.
