If Nail A is about 1 inch long and Nail B is about 1 3/4 inch long, what is their approximate difference in length?

Explanation:
Subtracting the lengths is the key idea here. Nail A is about 1 inch, Nail B is about 1 3/4 inches, so the difference is 1 3/4 minus 1, which equals 3/4 inch. So the gap between them is three quarters of an inch. The other numbers don’t fit because they’re either too small (1/4 inch), represent Nail B’s full length (1 3/4 inch), or are larger than the actual gap (1 1/4 inch).
