Problem
4) Last month, Gianni used \( 6 \mathrm{~GB} \) out of the \( 8 \mathrm{~GB} \) included in his cell phone plan. Lamar used \( 4 \mathrm{~GB} \) out of the \( 5 \mathrm{~GB} \) included in his plan. Who used a greater percent of his data? (4) What percent of his data did Gianni use? (1) Gianni: \( 75 \quad \% \) (1)) What percent of his data did Lamar use? Lamar: \( \% \)
Solution
Step 1 ：Gianni: \( \frac{6}{8} \times 100 = 75 \% \)
Step 2 ：Lamar: \( \frac{4}{5} \times 100 = 80 \% \)
Step 3 ：Lamar used a greater percent of his data.
