Question from Toyia, a parent: 12.87 profit from 21.99 sale. What is the percentage that was taken off the 21.99 |
Toyia,
If the profit was $12.87$ then the amount taken off is $21.99 - 12.87 = 9.12.$ Hence the fraction taken off is $\large \frac{9.12}{21.99}.$ To express this fraction as a percentage multiply by $100.$
