Fraction Values

You can choose fraction values up to a given denominator value, so that if you choose fifths, then you can get any denominator up to fifths, i.e. halves, thirds, quarters, fifths.

Fraction Types

For the generator you can either choose proper fractions, which is the default, Unit Fractions or improper fractions. Proper fractions have a numerator less than the denominator.

If you select Unit Fractions, all the fractions will have a numerator of 1.

If you select Improper Fractions the generator will create both proper and improper fractions.

Denominator Type

You can choose different denominator types depending on how difficult you want the questions to be.

You can select Like Denominators, where the denominators are both equal.

You can select Unlike Denominators, where they are both randomly generated.

You can select Denominator Multiples where one of the fractions has a denominator which is a multiple of the other denominator.

Operation Type

Choose whether you want Addition and Subtracting, just Addition or just Subtraction questions.

Negative Answers

If you allow negative answers, then it allows for the answer to be negative when subtracting fractions.

Missing Addends

Sometimes, you may want to add an extra layer of difficulty by providing an addition or subtraction fraction equation where one of the other fractions is missing (rather than the one after the = sign).

Having this feature turned on will create a missing fraction somewhere in the equation - it may be the first number, second number, or third number.

(Optional) Give your worksheet a title.

(Optional) Write out any instructions to go at the top of the sheet.
