Answer

Explanation:

Step1: Count the number of jumps

There are 10 equal - sized jumps on the number line.

Step2: Determine the size of each jump

The distance from 0 to 1 is divided into 4 equal parts, so each jump represents $\frac{1}{4}$.

Step3: Write the addition problem

The addition problem is $\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}$, and $\frac{1}{4}\times10=\frac{10}{4}$.

Answer:

B. $\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{10}{4}$
