Stretch: Exact Positions on the Number Line
I can place fractions and negative rational numbers precisely and find the number halfway between two values.
🧠 The Challenge
rational numbernumber linebetweenmidpoint
To place a fraction, split the unit into equal parts. The midpoint of two numbers is their average — exactly halfway between them.
👀 Worked Example
Halfway between 2 and 5 is (2 + 5) ÷ 2 = 3.5. Halfway between −4 and 0 is −2.
