Step-by-step explanation:
Fractions can be confusing. Let's convert them to decimals since they are all rational numbers. 12 1/2 → 12.5 5 1/4 → 5.25 2 1/2 → 2.5
Add the two numbers that indicate the amount of thread available.
5.25 + 2.5 = 7.75
Subtract that number from the amount of thread needed.
12.5 - 7.75 = 4.75
Convert back to a fraction.
4.75 → 4 3/4
