Simplify Fractions for Primary | DigiTransact Mastermind

What simplify fractions means

You learn how to reduce a fraction to its simplest form by dividing the top and bottom by the same number. This helps you write answers neatly and compare fractions more easily in later work.

What you will practise

Find a common factor for the top and bottom numbers
Divide both parts of a fraction by the same number
Check if the fraction can be reduced again
Write each fraction in its simplest form

Before you start

You should be comfortable with multiplication tables and simple division facts. It also helps to know the parts of a fraction, especially the numerator and denominator.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Simplify 4/8

1/4
1/2
2/3
3/4

Answer: 1/2

Working: Divide top and bottom by 4: 4÷4 = 1, 8÷4 = 2, giving 1/2.

Common mistakes to avoid

Dividing only the top or only the bottom, instead of both numbers
Using a number that does not divide both parts exactly
Stopping too early before the fraction is in simplest form
Changing the value of the fraction by using different divisors

Curriculum and exam alignment

Ghana GES Basic 4 to 6 syllabusGroundwork for the BECE

In Upper Primary, this usually comes after work on fractions as parts of a whole and before more advanced fraction operations. It supports school-based assessment and builds the foundation needed for BECE preparation.

Curriculum notes are a general guide to where this work normally sits. Always check the syllabus your school or examination body is currently using.
