1. What is the Fahrenheit equivalent for a patient's room that
needs to be kept at 25 degrees Celsius?
A) 70°
B) 75°
C) 77°
D) 80°
Answer: C) 77°
Rationale: The formula for converting Celsius to Fahrenheit is F =
(C × 9/5) + 32. For 25°C: (25 × 9/5) + 32 = 45 + 32 =
77°F .

,2. What is the Celsius equivalent for a patient who is running a
fever of 102 degrees Fahrenheit?
A) 37.9°C
B) 38.9°C
C) 39.9°C
D) 40.9°C
Answer: B) 38.9°C
Rationale: The formula for converting Fahrenheit to Celsius is C =
(F - 32) × 5/9. For 102°F: (102 - 32) × 5/9 = 70 × 5/9 =
38.9°C .
3. What is the value of x in this equation? 2x + 3 = 13
A) 5
B) 10
C) 76
D) 106
Answer: A) 5
2
,Rationale: To solve: 2x + 3 = 13, subtract 3 from both sides: 2x
= 10, then divide both sides by 2: x = 5 .
4. Solve the following equation: x − 5/4 = 2/3. What is the
value of x?
A) 3/12
B) 7/12
C) 10/12
D) 23/12
Answer: D) 23/12
Rationale: To solve: x = 2/3 + 5/4. Find a common denominator
(12): 2/3 = 8/12 and 5/4 = 15/12. Sum: 8/12 + 15/12 =
23/12 .
5. Convert the fraction 3/4 to a decimal.
3
, A) 0.25
B) 0.50
C) 0.75
D) 1.33
Answer: C) 0.75
Rationale: To convert a fraction to a decimal, divide the
numerator (3) by the denominator (4). 3 ÷ 4 = 0.75 .
6. Convert 0.625 to a fraction in simplest form.
A) 5/8
B) 3/5
C) 5/6
D) 2/3
Answer: A) 5/8
Rationale: 0.625 = 625/1000. Simplify by dividing numerator
and denominator by the greatest common factor (125): 625 ÷
125 = 5, 1000 ÷ 125 = 8, giving 5/8 .
