Question

Look at the following expression:

the fraction one half x 4 + 6 − 3

Where should a set of parentheses go in the expression to get a value of 2?

Group of answer choices

the fraction one half x (4 + 6) − 3

the fraction one half x 4 + (6 − 3)

( the fraction one half x 4) + 6 − 3

the fraction one half x (4 + 6 − 3)

Answer 1

• Option A

Explanation:

Verify the answer choices for the final value of 2.

A) the fraction one half x (4 + 6) − 3

• 1/2 × (4 + 6) - 3 = 1/2 × 10 - 3 = 5 - 3 = 2, correct

B) the fraction one half x 4 + (6 − 3)

• 1/2 × 4 + (6 - 3) = 2 + 3 = 5 ≠ 2, incorrect

C) ( the fraction one half x 4) + 6 − 3

• (1/2 × 4) + 6 - 3 = 2 + 6 - 3 = 5 ≠ 2, incorrect

D) the fraction one half x (4 + 6 − 3)

• 1/2 × (4 + 6 - 3) = 1/2 × 7 = 7/2 = 3 1/2 ≠ 2, incorrect
