Key Stage 3 · Ages 11–12 · Intermediate
Instructions: Show your working clearly and simplify each fraction where possible. For ordering questions, write the complete sequence in the requested order. Check that your answers are reasonable before moving on.
Add and subtract fractions
Find a common denominator before adding or subtracting. Simplify each answer fully and show your working.
1. 2/3 + 3/5 =
2. 7/8 − 1/6 =
3. 5/12 + 3/10 =
4. 11/15 − 2/9 = [3 marks each]
Work with mixed numbers
Convert to equivalent fractions where helpful. Give each final answer as a mixed number in its simplest form.
1. 1 1/4 + 2 2/3 =
2. 4 1/2 − 1 3/4 =
3. 2 5/6 + 1 3/8 =
4. 5 1/3 − 2 5/8 = [3 marks each]
Multiply and divide fractions
For multiplication, multiply the numerators and denominators, then simplify. For division, multiply by the reciprocal of the second fraction. Show your working.
1. 3/4 × 2/5 =
2. 5/6 × 3 =
3. 7/8 ÷ 2 =
4. 2/3 ÷ 4/5 = [3 marks each]
Fractions of amounts and quantities
To find a fraction of an amount, divide by the denominator and then multiply by the numerator. For a fraction of one quantity compared with another, write the first quantity over the second and simplify.
1. Find 3/5 of £40.
2. Find 7/8 of 56.
3. A box contains 18 red counters and 30 blue counters. What fraction of all the counters are red? Simplify your answer.
4. A recipe uses 150 g of flour and 250 g of sugar. Flour is what fraction of the mass of the sugar? Simplify your answer. [3 marks each]
Order fractions, decimals and percentages
Convert the values to a common form, such as decimals or percentages, before comparing them. Write each full sequence in the order requested.
1. Order from smallest to largest: 3/5, 0.58, 62%.
2. Order from largest to smallest: 7/10, 68%, 0.72.
3. Order from smallest to largest: 5/8, 0.6, 64%.
4. Order from largest to smallest: 3/4, 78%, 0.73. [3 marks each]
