Concept Formula Example
Percentage Part = Percent × Whole 20% of 50 = 10
Average (Mean) Sum ÷ Number of items (2+4+6)÷3=4
Ratio a:b = a/b 2:3 = 2/3
Proportion a/b = c/d → ad = bc 2/3 = 4/6 → 12=12
Fraction to Decimal Divide numerator by denominator 3/4 = 0.75
Decimal to Percent Multiply by 100 0.75 = 75%
Temperature °F = (°C × 9/5) + 32 37°C = 98.6°F
Temperature °C = (°F – 32) × 5/9 98.6°F = 37°C
IV Flow Rate mL/hr = Total mL ÷ Total hr 1000mL ÷ 8hr = 125mL/hr
Dosage Calculation Dose = (Ordered mg/kg) × Weight kg 5mg/kg × 70kg = 350mg
Order of Operations PEMDAS
Questions 1-75
Question 1
Convert 7/8 to a decimal.
,A) 0.75
B) 0.80
C) 0.875
D) 0.925
Answer: C) 0.875
Rationale: 7 ÷ 8 = 0.875. Memorize: 1/8 = 0.125, 2/8 = 0.25, 3/8 = 0.375, 4/8 = 0.5, 5/8
= 0.625, 6/8 = 0.75, 7/8 = 0.875, 8/8 = 1.0.
Question 2
What is 35% of 80?
A) 20
B) 24
C) 28
D) 32
Answer: C) 28
Rationale: 35% = 35/100 = 0.35. 0.35 × 80 = 28. Alternative: 10% of 80 = 8, 30% = 24,
5% = 4, total = 28.
Question 3
Solve: 24 + 6 × 3 – 8 ÷ 2
, A) 28
B) 34
C) 38
D) 44
Answer: C) 38
Rationale: Order of operations: Multiplication and division first (left to right). 6 × 3 = 18.
8 ÷ 2 = 4. Then addition and subtraction: 24 + 18 = 42. 42 – 4 = 38.
Question 4
A patient drank 360 mL of water, 240 mL of juice, and 120 mL of broth. What is the total
intake in liters?
A) 0.72 L
B) 0.72 L
C) 7.2 L
D) 72 L
Answer: A) 0.72 L
Rationale: Total mL = 360 + 240 + 120 = 720 mL. 1 L = 1000 mL, so 720 mL = 0.72 L.
Question 5
What is the least common denominator for 1/2, 2/3, and 3/4?
