Stage 8 - Q1 - 2 marks
18217

Insert \(<\), \(>\) or \(=\).

\[\frac{2}{9}\quad\square\quad\frac{5}{9}\]
Hint

Equal denominators mean equal-sized parts.

Stage 8 - Q2 - 2 marks
18218

Insert \(<\), \(>\) or \(=\).

\[\frac{3}{7}\quad\square\quad\frac{3}{10}\]
Hint

The numerator is the same; compare the part sizes.

Stage 8 - Q3 - 2 marks
18219

Insert \(<\), \(>\) or \(=\).

\[\frac{7}{10}\quad\square\quad\frac{2}{3}\]
Hint

Use a denominator divisible by both 10 and 3.

Stage 8 - Q4 - 3 marks
18220

Order from smallest to largest.

\[\frac{3}{4},\ \frac{7}{9},\ \frac{5}{6}\]
Hint

Use a common denominator for all three fractions.

Stage 8 - Q5 - 2 marks
18221

Leila scores 19 out of 25. Omar scores 31 out of 40. Who has the higher proportion?

Hint

The larger raw score is not enough; compare fractions.

Stage 8 - Q6 - 2 marks
18222

Find a fraction strictly between \(\frac{5}{8}\) and \(\frac{2}{3}\).

Hint

A larger common denominator may create space between the numerators.

Stage 8 - Q7 - 2 marks
18223

Without decimal division, compare \(\frac{48}{49}\) and \(\frac{69}{70}\).

Hint

Compare how far each fraction lies below 1.

Stage 8 - Q8 - 2 marks
18224

Find all integers n for which \(\frac{1}{2}<\frac{n}{10}<\frac{4}{5}\).

Hint

The inequalities are strict, so exclude the endpoints.

Stage 8 - Q9 - 4 marks
18225

A pupil says \(\frac{a}{b}<\frac{a+1}{b+1}\) for all positive a and b. Give a counterexample and explain when it fails.

Hint

Try a fraction greater than 1.

Stage 8 - Q10 - 5 marks
18226

Challenge: find all integers n such that \(\frac{3}{7}<\frac{n}{12}<\frac{4}{5}\), and prove there are no others.

Hint

Turn each fraction comparison into a bound on n, then inspect the integers.
