- 20%
- 80%
- 125%
- 400%
Need a hint?
Divide the cost of the mangoes by the amount paid, then convert the fraction to a percentage.
Worked answer
- Cost as a fraction of the amount paid: $4 ÷ $5 = 45.
- Convert to a percentage: 45 × 100% = 80%.
Answer: 80%

Habit
Calculation slip
Dividing $5 by $4 gives 125%. This reverses the comparison because the cost is the part and $5 is the whole.
