Question

what is the position of b on the number line below? write your answer as a fraction or mixed number.

Explanation:

Step1: Determine unit - length

The distance between 1 and 2 (and other consecutive whole - numbers) is divided into 5 equal parts. So the unit length of each small segment is $\frac{1}{5}$.

Step2: Locate B

Point B is 1 unit to the right of 2. Since each unit is divided into 5 equal parts and B is 1 part to the right of 2, the position of B is $2+\frac{1}{5}=\frac{10 + 1}{5}=\frac{11}{5}=2\frac{1}{5}$.

Answer:

$2\frac{1}{5}$
