To find out how much wrapping paper Solo will have left over, we need to subtract the total length of paper used from the total length of the roll.

1. Calculate the total length of paper used:
- For wrapping a present for her sister: 1.25m
- For wrapping a present for her dad: 2.8m
Total length used = 1.25m + 2.8m = 4.05m

2. Subtract the total length used from the total length of the roll:
Total length of the roll = 4.5m
Paper left over = Total length of the roll - Total length used
Paper left over = 4.5m - 4.05m = 0.45m

Therefore, Solo will have 0.45 meters of wrapping paper left over.
