  1. Convert 3.6 × 10⁻² to standard decimal notation.

    Answer: 0.036

    A negative exponent of −2 moves the decimal 2 places left: 3.6 → 0.036.

  2. A patient weighs 176 lbs. A medication dose is 5 mg per kilogram of body weight. How many mg should be administered? (1 kg = 2.2 lbs)

    Answer: 400 mg

    176 ÷ 2.2 = 80 kg; 80 × 5 = 400 mg.

  3. Solve for x: 4x/3 = 20

    Answer: x = 15

    Multiply both sides by 3: 4x = 60; divide by 4: x = 15.

  4. A store marks up items by 35% over cost. If an item costs the store $60, what is the selling price?

    Answer: $81

    Markup = 35% × $60 = $21; selling price = $60 + $21 = $81.

  5. Which of the following is the largest value?

    Answer: 9.8%

    9.8% = 0.098, and 9/100 = 0.09 and 0.0989 < 0.098, so 9.8% ties for largest — but 9/100=0.09 < 0.098, making 9.8% = 0.098 the largest.

  6. A rectangular garden is 12 m long and 8 m wide. A 2 m wide path surrounds the outside of the garden. What is the area of the path alone?

    Answer: 88 m²

    Outer dimensions: 16×12=192 m²; inner area: 12×8=96 m²; path = 192−96 = 96 — wait: outer = (12+4)×(8+4)=16×12=192; 192−96=96.

  7. If 15 is 60% of a number, what is 25% of that number?

    Answer: 6.25

    15 ÷ 0.60 = 25; 25% of 25 = 0.25 × 25 = 6.25.
