Question

Which number line correctly shows 1. 5 + 2. 5? A number line going from 0 to 6. 5 in increments of 0. 5. An arrow goes from 0 to 1. 5 and from 1. 5 to 4. A number line going from 0 to 6. 5 in increments of 0. 5. An arrow goes from 0 to 1. 5 and from 1. 5 to 3. A number line going from 0 to 6. 5 in increments of 0. 5. An arrow goes from 0 to 2. 5 and from 2. 5 to 5. A number line going from 0 to 6. 5 in increments of 0. 5. An arrow goes from 1. 5 to 3 and from 3 to 5. 5.

Answer 1

So we want to see which number line shows the sum 1.5 + 2.5. We will see that the correct option is "An arrow goes from 0 to 1. 5 and from 1. 5 to 4"

So the number line usually starts at 0 and goes to the first number, 1.5 in this case.

Then, it moves accordingly to the second number, 2.5 (so it will move 2.5 units to the right)

So the number line should start at 0 and move to the right until it meets 1.5 + 2.5 = 4.

From the options, the only that is correct is:

"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"
