To calculate:To find that Carlita and Len are writing a percent of input & which one is correct, with reason.

Answer to Problem 45HP

Len’s answer is the correct answer.

Explanation of Solution

Given information:

Carlita answer $1.5=1.5÷100$ or $0.015\%$

Len’s answer $1.5=1.5\times 100$ or $150\%$

Calculation:

Asper given information,

Carlita answer $1.5=1.5÷100$ or $0.015\%$

Len’s answer $1.5=1.5\times 100$ or $150\%$

Len’s answer is correct because Carlita divided by $100$ and Len should have multiplied by $100$

And for writing $1.5$ as a percent, turn the decimal into a percent multiply $1.5$ by $100$

Hence, Len’s answer is correct and Carlita’s answer is wrong.
