Find the whole. \( 85 \% \) of what number is 17 ?

To find the whole number from the percent, you can use the formula: Whole number = Part / (Percent / 100). In this case, the part is 17, and the percent is 85. So, plugging in the numbers gives you: Whole number = \( 17 / (85 / 100) = 17 / 0.85 = 20 \). Thus, the whole number is \( 20 \). Now, if you want to apply this practically, think of it like a sale. If an item priced at $20 is 85% off, you’d effectively be getting it for $17. Understanding percentages can really help you score great deals while shopping! As for common mistakes, be careful with your calculations when converting percentages. Many tend to confuse calculating the percentage with finding the whole; double-check your math to avoid getting lost in numbers!
