Final answer:
To represent 1/4, divide a circle into four equal sections and shade one of them.
Step-by-step explanation:
To model the fraction 1/4, you would divide the circle into 4 equal sections since the denominator of the fraction tells us into how many equal parts the whole is divided.
After dividing the circle, you need to shade the number of sections that corresponds to the numerator of the fraction. In this case, to represent 1/4, you would shade only one of the four equal sections of the circle.
