A temperature of 45 degrees C is equal to ____ degrees F

• A. 101 degrees
• B. 113 degrees
• C. 98 degrees
• D. 45 degrees

Answer: (B)

To convert Celsius to Fahrenheit, multiply by 9/5 and then add 32. For 45 degrees Celsius: 45 × 9/5 = 45 × 1.8 = 81, and 81 + 32 = 113. So 45°C equals 113°F. A quick check using known reference points shows the relationship is linear: 0°C is 32°F and 100°C is 212°F, which fits this conversion.
