Question 

Without using a calculator, work out \( 5\frac{1}{3} – 3\frac{4}{7}\)

You must show all your working and give your answer as a mixed number in its simplest form.

▶️ Answer/Explanation
Solution

Ans: 1¹⁶⁄₂₁

Convert to improper fractions: 16/3 – 25/7.

Find common denominator (21): 112/21 – 75/21 = 37/21.

Convert to mixed number: 1¹⁶⁄₂₁.

Question 

The diagram shows part of a regular polygon.
The interior angle of the polygon is 132° larger than the exterior angle.

Calculate the number of sides of this polygon.

▶️ Answer/Explanation
Solution

Ans: 15

Let exterior angle = x, then interior = x + 132.

They sum to 180°: x + (x + 132) = 180 → x = 24°.

Number of sides = 360°/24° = 15.

Question 

The diagram shows a trapezium.

The area of the trapezium is 42 cm²

Calculate the value of x.

▶️ Answer/Explanation
Solution

Ans: 4.5 cm

Area = ½ × (sum of parallel sides) × height

42 = ½ × (9.5 + x) × 6

14 = 9.5 + x

x = 4.5 cm
