Question

1. find the sum.

$3 + \frac{1}{2} = \square$
(number line from 0 to 5, and a number pad at the bottom right)

Explanation:

Step1: Identify the operation

We need to add the whole number 3 and the fraction $\frac{1}{2}$.

Step2: Add the numbers

To add a whole number and a fraction, we combine them. So, $3+\frac{1}{2}$ can be written as a mixed number. We know that $3$ is the same as $\frac{6}{2}$, so $\frac{6}{2}+\frac{1}{2}=\frac{7}{2}$ or as a mixed number $3\frac{1}{2}$. Looking at the number line, we start at 3 and move $\frac{1}{2}$ unit to the right, which lands us at $3\frac{1}{2}$.

Answer:

$3\frac{1}{2}$ (or $\frac{7}{2}$)
