Darla answered 28 questions incorrectly.

Solución

1. Darla earned \(72\%\) on her test. Since there were \(100\) questions, the number of questions she answered correctly is: \[ 0.72 \times 100 = 72 \] 2. To find the number of questions she answered incorrectly, subtract the number of correct answers from the total number of questions: \[ 100 - 72 = 28 \] Thus, Darla answered \(28\) questions incorrectly.

Beyond the Answer

Darla answered \( 72 \) questions correctly since \( 72\% \) of \( 100 \) is \( 72 \). To find out how many questions she answered incorrectly, you simply subtract the number of correct answers from the total: \( 100 - 72 = 28 \). So, she answered \( 28 \) questions incorrectly. Understanding how percentages work can be super helpful in various real-life situations, like figuring out your savings from a sale or assessing your performance in a class. Don't underestimate the power of percentages—they're everywhere! Plus, mastering this concept can help you tackle similar problems with confidence!

How can you tell that \( (448+217+34) \times 9 \) is three times as large as \( (448+217+34) \times 3 \) without doing complicated calculations? Compare the parts that are the same. The first expression shows a sum multiplied by a multiple of 3 . The second shows the same sum multiplied by a multiple of 3 . So, the two expressions are both 3 times as large as the sum. Compare the parts that are the same. The first expression shows a sum multiplied by a number. The second shows the same sum multiplied by a number. So, both expressions must be greater than the sum. Compare the parts that are different. The first expression shows a sum multiplied by 9 . The second shows the same sum multiplied by 3 . So, the first expression is three times as large as the second expression. Compare the parts that are different. The first expression shows a sum multiplied by 9 . The second shows the same sum multiplied by 3 . So, the first expression must be less than the second expression.
