Problem
(1) During the summer, Isabelle sells corn at her family's produce stand. Every morning, she starts with 250 ears of corn. On Saturday, Isabelle sells 150 of the 250 ears of corn. She wants to know what percent of the corn she sold. (1)) Complete the table to show an equivalent ratio where the number of ears at the start is 100. \begin{tabular}{|c|c|c|} \hline \multicolumn{1}{|c|}{ Corn Sold } & 150 \\ \hline Corn at Start & 250 & 100 \\ \hline \end{tabular}
Solution
Step 1 ：\frac{150}{250} = \frac{x}{100}
Step 2 ：x = \frac{150 \times 100}{250}
Step 3 ：x = 60
