Express 120¢ as a percentage of $1.50.
- 8%
- 80%
- 125%
- 800%
Need a hint?
Both amounts must be in the same unit before you divide. Change $1.50 into cents first.
Worked answer
- Write $1.50 in cents: $1.50 = 150¢.
- Write the fraction: 120¢ out of 150¢ = 120/150.
- Simplify: 120/150 = 4/5.
- Change to a percentage: 4/5 = 0.8 = 80%.
Answer: 80%
