Fraction Visualizer: Fraction Circles and Bars
Draw a fraction as a shaded circle and bar, see its simplest form, decimal, percentage, mixed number, and equivalent fractions, and put two fractions side by side to see which is bigger.
Fraction Visualizer: Fraction Circles and Bars: The whole is cut into as many equal parts as the denominator and the numerator's worth are shaded. 6/8 shades six of eight slices, simplifies to 3/4, and is 0.75 or 75%. To compare 3/4 with 2/3, cross-multiply: 3 × 3 = 9 against 2 × 4 = 8, so 3/4 is bigger. Fractions above one, such as 7/3, fill more than one shape and show as 2 1/3.

3/4 · 0.75 · 75%
Equivalent: 6/8, 9/12, 12/16, 15/20
2/3 · 0.6667 · 66.67%
Equivalent: 4/6, 6/9, 8/12, 10/15
3/4 is bigger than 2/3
The denominator says how many equal parts the whole is cut into, and the numerator how many are shaded. Fractions bigger than one fill more than one shape. To compare two fractions, cross-multiply: 3/4 against 2/3 is 9 against 8, so 3/4 is bigger.
Circles or bars?
Circles show a fraction as part of a whole, like slices of pizza; bars line up well for comparing and for adding fractions with the same denominator. Showing both helps children see that the shape does not change the amount.

Frequently asked questions
Why do 2/4 and 1/2 look the same?
They are equivalent: the same amount cut into more, smaller pieces. Dividing the top and bottom by the same number, here 2, gives the simplest form.
How do I compare fractions without drawing them?
Cross-multiply, or rewrite both with the same denominator: 3/4 is 9/12 and 2/3 is 8/12.
Can I show improper fractions?
Yes: numerators up to twice the denominator fill a second shape, so 5/4 shows as one whole and a quarter.
