Solve for y: y/5 = 9.

Explanation:
When you see y/5 = 9, the operation that undoes division by 5 is multiplication by 5. Multiply both sides by 5 to isolate y: (y/5)·5 = 9·5, so y = 45. This works because 45 divided by 5 equals 9, confirming the solution. The other numbers don’t fit because 9 would give 9/5, 5 would give 1, and 54 would give 10.8 when divided by 5. The correct value is y = 45.
