Answer:
The benchmark fraction she will use is 5/8.
Step-by-step explanation:
Benchmark Fractions are guides that help us find other fractions. Fractions that are more known are used to find less common fractions.
The two Benchmark Fractions we will use are 1/2 and 3/4 because they are close but not exact. We know that Tina has a number in between these because we know Tina will use more than 1/2 but less than 3/4.
To find the benchmark fraction, we take the average of 1/2 and 3/4. The way to do this is by adding the two fractions together and dividing by two.
(1/2 + 3/4) / 2 = (2/4 + 3/4) / 2 = 5/8
In conclusion, the fraction Tina will use is 5/8. Which is more than 1/2 but less than 3/4.
