Question

What number line model represents the expression 2.5+4.5

Choose 1 answer: A, B, or C?

​

Answer 1

A

Explanation:

Because, the first point will be plotted at 2.5 (each line is 1 which means like line after 0 is 1, the next one is 2, and so one). When you add 2.5 with 4.5 it equals to 7 which means the next point will be placed at 7. (right behind 8)
