Question

mrs. fermat just finished grading math tests. she wants to know how each student’s score on this test compares to his or her score on the previous test. she gathers that information for four students in the table.

student	change in test score
dulce	6
leo	-12
jenny	-4

which student’s test score changed the most?
kenneth
dulce
leo
jenny

Explanation:

Step1: Find absolute values

To determine which score changed the most, we find the absolute value of each change.

• Kenneth: $|10| = 10$
• Dulce: $|6| = 6$
• Leo: $|-12| = 12$
• Jenny: $|-4| = 4$

Step2: Compare absolute values

Compare the absolute values: $12 > 10 > 6 > 4$. Leo’s absolute value (12) is the largest.

Answer:

Leo
