1. Reduce the fraction 24/36 to lowest terms.
a. 12/18
b. 8/12
c. 2/3
d. 3/4
Answer: c. 2/3
Rationale: To reduce a fraction, find the greatest common divisor
(GCD) of numerator and denominator. The GCD of 24 and 36 is
12. 24 ÷ 12 = 2, 36 ÷ 12 = 3, resulting in 2/3.
2. Add the fractions: 3/8 + 1/4.
a. 4/12
,Page 2 of 125
b. 5/8
c. 1/2
d. 1/4
Answer: b. 5/8
Rationale: Find a common denominator (8). 1/4 = 2/8. Then
3/8 + 2/8 = 5/8. Always check whether the answer can be
reduced.
3. Subtract: 7/12 − 2/6.
a. 5/12
b. 1/4
c. 3/12
d. 1/12
Answer: b. 1/4
Rationale: Convert 2/6 to 4/12. Then 7/12 − 4/12 = 3/12 =
1/4.

4. Multiply: 3/5 × 2/3.
a. 6/15
b. 2/5
c. 1/2
d. 3/10
Answer: b. 2/5
Rationale: Multiply numerators: 3 × 2 = 6. Multiply
denominators: 5 × 3 = 15. 6/15 reduces to 2/5 (divide both by
3).
5. Divide: 2/3 ÷ 4/5.
a. 8/15
b. 10/12
c. 5/6
d. 3/5
, Page 4 of 125
Answer: c. 5/6
Rationale: To divide fractions, multiply by the reciprocal of the
divisor. 2/3 × 5/4 = 10/12 = 5/6.
6. A patient is to receive 3/4 of a medication dose. If the full
dose is 200 mg, what amount should the patient receive?
a. 75 mg
b. 100 mg
c. 150 mg
d. 175 mg
Answer: c. 150 mg
Rationale: Multiply 200 mg by 3/4: 200 × 3/4 = 600/4 =
150 mg. Alternatively, 200 ÷ 4 = 50, then 50 × 3 = 150.
7. Convert the improper fraction 17/5 to a mixed number.
a. 3 1/5
b. 3 2/5
