Fractions as equal parts
A fraction describes equal parts of a whole. In 3/4, the denominator 4 tells you how many equal parts make the whole; the numerator 3 tells you how many are selected. Parts must be equal for this model to work.
Worked example
Draw a rectangle split into four equal boxes. Shade three. Half of the same rectangle would shade two boxes, so 3/4 is greater than 1/2.
Try it yourself
A strip has eight equal sections and three are shaded. What fraction is shaded?
Reveal the answer and reasoning
3/8. Eight is the number of equal parts in the whole; three is the selected number.
