The bottom number (denominator) tells us number of equal pieces the bar should be broken into. The top number (numerator) tells us the number of pieces we should shade.

The fraction \dfrac{1}{2} tells us that we need to divide the shape into 2 equal parts with 1 part being shaded. This means the correct answer is Option C.

The missing fraction should be written as: \dfrac{\text{Number of spaces from zero}}{\text{Total number of equal spaces}}

There are 5 equal spaces on the number line. We are counting up 3 spaces from 0 to get to the missing number.

\text{Missing number}=\dfrac{3}{5}
