17. \( 10 \% \) of ___ is 7

To find out what number \( x \) makes \( 10\% \) equal to \( 7 \), we can set up the equation \( 0.1x = 7 \). By dividing both sides by \( 0.1 \), we discover that \( x = 70 \). Thus, \( 10\% \) of \( 70 \) is indeed \( 7 \). This equation illustrates the concept of percentages in math, which are crucial for various applications. From calculating discounts while shopping to understanding statistics in daily news articles, percentages help us make sense of quantities in a relative manner. So the next time you're getting a deal or looking at survey results, you'll see the power of these little numbers!
