Problem
As a part of his science experiment, Ethan recorded the number of days it rained in April. Over the 30 days, it rained 15 days. Ethan wants to know what percent of the days in April it rained. (1) Complete the equivalent fraction to show the number of days it rained for every 2 days in April. \[ \frac{15}{30}=\frac{1}{2} \] (1)) What percent of the days did it rain in April? percent: \( \square \)
Solution
Step 1 ：Convert the fraction \(\frac{1}{2}\) to a percentage by multiplying it by 100
Step 2 ：Calculate the percentage : \(\frac{1}{2} \times 100 = 50\)
Step 3 ：percent: \(50\)
