Question

Reasoning: Vanessa scored 78% on a test with 120 questions. What benchmark fraction would you use to estimate the number of questions that Vanessa answered correctly?

Answer 1

benchmark fraction 4/5

Vanessa answered correctly 96

Explanation:

78% ≈ 80%

80% = 80/100

80%m = 8/10 = 4/5

120 * 4/5 = 96

Answer 2

468 / 5

Explanation:

She scored 78% in a test of 120 questions.

We'll have to find the number of questions she got correctly

78% of 120 =

78 / 100 = x / 120

Cross multiply both sides

100x = 78 × 120

100x = 9360

X = 9360 / 100

X = 468 / 5

The benchmark fraction to estimate the number she answered correctly is 468 / 5
