Question

4 for his exercise last weekend, benito walked 5 miles and jogged 2 miles. what is the ratio of the miles walked to the total number of miles of exercise?
a 5 to 2
c 5:7
b 2:7
d 7 to 5
elsa chose a as the correct answer. how did she get that answer?
are you finding a ratio that compares part to part or part to whole?

Explanation:

Part 1: Correct Ratio of Miles Walked to Total Miles

Step 1: Find total miles of exercise

Benito walked 5 miles and jogged 2 miles. Total miles = miles walked + miles jogged = \( 5 + 2 = 7 \) miles.

Step 2: Find the ratio of miles walked to total miles

Ratio of miles walked to total miles = miles walked : total miles = \( 5 : 7 \). So the correct answer is C. 5:7.

Elsa likely compared the miles walked (5) to the miles jogged (2) instead of to the total miles. She thought the ratio was part - to - part (walked to jogged) instead of part - to - whole (walked to total). So she used 5 (walked) and 2 (jogged) to form the ratio 5 to 2.

Answer:

C. 5:7
