Final answer:
The number closest to 7 is 46.
Step-by-step explanation:
The number closest to 7 is 7 itself. None of the options provided in the question are exactly 7, so we need to find the number that is closest to 7. To do this, we can calculate the absolute difference between each option and 7, and choose the option with the smallest difference. Let's calculate the absolute differences:
- Absolute difference between 7 and 47: |7 - 47| = 40
- Absolute difference between 7 and 46: |7 - 46| = 39
- Absolute difference between 7 and 50: |7 - 50| = 43
- Absolute difference between 7 and 51: |7 - 51| = 44
Based on the calculations, the option closest to 7 is B. 46, with an absolute difference of 39.
