Converting between fractions and decimals, including common equivalents (½ = 0.5, ¼ = 0.25).
Where your child meets this in real life: Converting between formats when calculating or comparing (e.g., test scores)
Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.
SEAGReady breaks convert fractions and decimals into 3 steps, taught in order so each skill builds on the last.
Recognise and convert common fraction-decimal pairs (halves, quarters, fifths, tenths) using memorisation or simple division
Convert fractions to decimals of up to two decimal places by treating the fraction bar as a division operator
Convert terminating decimals to simplified fractions by identifying place value, creating an equivalent fraction, and simplifying if necessary
Try three free questions from our convert fractions and decimals course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.
Aoife needs half a litre of milk. The strips show the same amount as 1/2 and 5/10. What decimal amount should she pour?
Nathan used 13/20 of a tin of paint. The division setup is shown. What is this amount as a decimal?
A recipe calls for 0.35 kg of flour. Alfie only has measuring cups marked in fractions. What fraction of a kilogram does he need?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Amelia is baking scones and the recipe calls for half a cup of sugar. Her measuring cup only shows decimal markings.
What decimal should she measure to get exactly half a cup?
½ = ?
Half means 1 out of 2 equal parts
Step 1 of 3
Amelia is baking scones and the recipe calls for half a cup of sugar. Her measuring cup only shows decimal markings.
What decimal should she measure to get exactly half a cup?
Amelia should measure 0.5 on her cup to get half.
The key insight: Memorise the key pairs: ½ = 0.5, ¼ = 0.25, ¾ = 0.75, ⅕ = 0.2!
Common mix-up: ½ = 0.2. The denominator 2 is not the decimal. Half means 5 tenths, which is 0.5.
These are the misconceptions we see most often in convert fractions and decimals, including the ones our practice questions are specifically designed to catch.
Struggling with convert fractions and decimals? The real gap is often in one of these earlier topics.
