13.9 .8 is \( 14 \% \) of what number?

To find out what number \( 13.9 \) is \( 14\% \) of, you can set up the equation \( 13.9 = 0.14 \times X \), where \( X \) is the number you're looking for. By rearranging the equation to solve for \( X \), you would divide \( 13.9 \) by \( 0.14 \): \[ X = \frac{13.9}{0.14} \approx 99.2857 \] So, \( 13.9 \) is \( 14\% \) of approximately \( 99.29 \). Also, a fun way to remember percentage calculations is to visualize them as a pie chart! Picture the whole pie as the 100%, and then each percentage slice represents the relevant part. In this case, \( 14\% \) is just a little under one-sixth of the pie, making it flavorful and easier to understand the concept of fractions and percentages together! Additionally, a common mistake in percentage calculations is forgetting to convert the percentage to a decimal. It’s essential to shift that percent sign to the left by two places before performing any calculations—this quick tip can save you from many wrong turns in your math journeys!
