  1. Evaluate 3/4 + 1/2 × 2.

    Answer: 1 3/4

    Multiply first: 1/2 × 2 = 1. Then 3/4 + 1 = 1 3/4.

  2. A $120 jacket is discounted 30%. What is the sale price before tax?

    Answer: $84

    The discount is $36, so the sale price is $120 − $36 = $84.

  3. Which decimal equals 7.5%?

    Answer: 0.075

    Divide the percent by 100: 7.5% = 0.075.
