MA62052.205 MS MATH 6 - NISTLER DUE PRACTICE TEST:Topic 6 Final TesE: Percents Feb 26 - 11:59 pm There are 500 sheets of printer paper in a package. Erin uses \( 18 \% \) of the paper when she prints a report for social studies class. About how many sheets of paper does Erin use for her report? Explain. \( 18 \% \) is about \( \square \) This estimated percent as a fraction is \( \square \) . So, Erin used about that amount of the total sheets, or about \( \square \) sheets. (Type integers or fractions.)

To find how many sheets of paper Erin uses for her report, we start with 18% as a decimal, which is \( 0.18 \). The fraction equivalent is \( \frac{18}{100} \) or simplified to \( \frac{9}{50} \). Now, we calculate \( 18\% \) of 500 sheets: \[ 500 \times 0.18 = 90 \] So, Erin used about **90 sheets** of paper for her report. Now, it's fun to think about how this could translate into real-world applications! For example, the same percentage concept applies when budgeting. If you have $500 and decide to save 18%, you’d save $90. It's a handy way to keep track of both expenses and savings! In terms of problem-solving, one common mistake is forgetting to convert the percentage into a decimal or fraction before multiplying. Always check your work by estimating first; rounding 18% to a nearby benchmark, like 20%, can sometimes give you a quicker sense of the outcome before refining the exact calculations!
