FC0-U71 Tech Concepts and Terminology Practice Question
A student is converting the hexadecimal number 2F to decimal. What is the correct decimal value?
⚠ Common exam trap
FC0-U71 often tests number-system conversions where candidates forget that hex letters (A–F) map to 10–15, leading them to misread 'F' as a decimal digit or skip it entirely.

Correct answer & explanation
✓
47
Hexadecimal is base-16, so each digit represents a power of 16. For 2F, the '2' is in the 16s place (2 × 16 = 32) and 'F' represents 15 in the 1s place (15 × 1 = 15). Adding these gives 32 + 15 = 47, which is the correct decimal equivalent.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
59
Why it's wrong here
2F equals 2×16 + 15 = 47, not 59. The value 59 arises from misreading F as 11 or from adding the digits incorrectly, so it reflects an arithmetic slip rather than the correct positional weighting of hexadecimal digits.
- ✗
32
Why it's wrong here
2F equals 47, not 32. The value 32 corresponds to 20 in hexadecimal (2×16 + 0), meaning the low nibble F was treated as zero rather than 15, so the second digit's weight was ignored.
- ✗
63
Why it's wrong here
2F evaluates to 47, not 63. The value 63 corresponds to 3F (3×16 + 15), showing the high nibble was misread as 3 instead of 2, so the positional weighting of the first digit is wrong.
- ✓
47
Why this is correct
Hexadecimal 2F converts by expanding place values: 2 × 16¹ = 32, and F represents 15, so 15 × 16⁰ = 15. Summing 32 + 15 gives 47, satisfying the stem's requirement to convert 2F to its decimal equivalent.
