(7) \( 95 \% \) of what number is 57 ?

To find the number for which 95% equals 57, you can set up the equation \( 0.95x = 57 \). By solving for \( x \), you would divide both sides by 0.95. Doing the math gives \( x = \frac{57}{0.95} \), which equals 60. Therefore, 95% of 60 is indeed 57! It’s fun to note that percentages are used in everyday life in various situations like sales, or determining tips. When you get a discount, for example, you’re calculating a percentage of the original price. So understanding how to manipulate these percentages can really come in handy when you're shopping – or dining out! If you ever need to calculate a percentage, make sure you’re clear on how to manipulate the equation. A common mistake is thinking in whole numbers instead of decimal form. Remember, to find "x% of a number," convert the percentage to a decimal and multiply it by the number. Familiarizing yourself with this can save you time and prevent errors!
