# Fractions exercises - exercises online and as PDF

We want to practise fractions intensively here.

Afterwards we practise Reducing and extending.

Can you Fractions in decimals or in Percentages convert? This is another topic!

Fractions, decimals and percentages can represent equal values. But if they are different, you can also arrange them from small to large. We have done some online exercises on this.

When we have mastered all these tasks, we will move on to fractions: Addition and subtraction, multiplication and division!

## Fraction tasks PDF worksheet and online exercise

Two worksheets for the following online exercises. Simply print them out and practise on paper or fill them in on your tablet with a pen.

As a test or class work for an easy introduction to fractions! Are you fit?

## online Exercise - Addition of fractions with equal denominators

Fractions Exercises - Exercise (1) Fractions with equal denominators

Enter only the numerator of the fraction in the empty field as the result!

Fraction exercises - Exercise (2) Fractions with equal denominators

Enter only the numerator of the fraction in the empty field as the result!

Worksheets Addition and and Subtraction with Equal Denominators

## Adding and subtracting unequal fractions

#### So you can add and subtract fractions if they do NOT have the same denominator (are not of the same name).

Fractions with different denominators can only be added or subtracted when the denominators are the same. To do this, you have to reduce and/or expand the fractions until they have the same denominator.

The common denominator (main denominator) results from the smallest common multiple of all denominators involved!

Examples:

(1) $$\frac{1}{3} +\frac{1}{4} = \frac{1\cdot 4}{3 \cdot 4} + \frac{1 \cdot 3}{4 \cdot 3} = \frac{4}{12} +\frac{3}{12} = \frac{7}{12}$$

(2) $$\frac{2}{9} +\frac{1}{6} = \frac{2\cdot 2}{9 \cdot 2} + \frac{1 \cdot 3}{6 \cdot 3} = \frac{4}{18} +\frac{3}{18} = \frac{7}{18}$$

You can also find more theory about fractions on Wikipedia

Normally you do this in fractions grade 5.

Exercise (1) - Find the same denominator of 2 fractions and then add the fractions.Add the missing numbers to the numerator of the fraction. Look carefully. The common denominator of the fractions is already there!

Exercise (2) - Find the same denominator of 2 fractions and then add the fractions.

Add the missing numbers to the numerator of the fraction. Look carefully. The common denominator of the fractions is already there!

Exercise (3) - Write down the task and then work it out!

Add the missing numbers to the numerator and denominator of the fraction.

Worksheets simple fractions addition and subtraction with different denominators

The tasks from the exercises type (III) as PDF for printing:

Exercise (4) - Addition of fractions and colouring in

These fractions tasks with solutions tasks are only available as worksheets PDF for printing. Here is an example of how the tasks look:

## Fraction tasks with solutions PDF and online

We first add and subtract two fractions and find the main denominator and then the solution. Then we calculate tasks with several summands and also with brackets!

Exercise (5) - Add, subtract and find the main denominator of the fractionEnter the main denominator in the box and write down the result in the form$$\frac{A}{B}$$ Give the Numerator of the fraction in field A and the Denominator of the fraction in field B on!
