Question

*24. the number that corresponds to point a is how much less than the number that corresponds to point b? (decimal answer)
number line with points a and b, and labels 7, 8, 9

Explanation:

Step1: Determine values of A and B

Assume the number line: From 7 to 8, let's say A is at 7.25 (since between 7 and 8, maybe divided into 4 parts, so each part is 0.25, A is 1 part from 7: \( 7 + 0.25 = 7.25 \)). From 8 to 9, B is at 8.75 (divided into 4 parts, each 0.25, B is 3 parts from 8: \( 8 + 0.75 = 8.75 \)).

Step2: Calculate the difference

Subtract A's value from B's value: \( 8.75 - 7.25 = 1.5 \)

Answer:

1.5
