Fraction Chart – Fractions to Decimals and Percents (Printable)

Every fraction from halves to sixteenths with its decimal and percent, a fraction wall to compare sizes, inch fractions in decimals and millimetres, and equivalent fractions. Tap any fraction for its full working.

Fraction wall

Each strip is one whole cut into equal parts. Pieces that line up are the same size: 1/2 = 2/4 = 3/6 = 4/8 = 6/12.

Frequently asked questions

How do you read a fraction chart?

Find the fraction in the left column; the same row gives its decimal and its percent. On the fraction wall, strips of the same length are equal: two 1/4 pieces line up with one 1/2.

Which fractions give repeating decimals?

Those whose denominator (in lowest terms) has a prime factor other than 2 or 5 – thirds, sixths, sevenths, ninths, elevenths, twelfths and so on. Halves, quarters, fifths, eighths, tenths and sixteenths all end.

What is 1/8 of an inch in decimals and millimetres?

1/8 inch is 0.125 inch, which is 3.175 mm (an inch is exactly 25.4 mm).

How do I print the fraction chart?

Use the Print button above the chart (or your browser’s print command). The menus and sidebars are left out, so the chart fits on the page.
