(2marks)

The length of the headline on the enlarge copy is 10 cm

Step-by-step explanation:

A photographer enlarges copies in the ratio 5 : 4

That means the copies will be of the original copies

The length of the headline "BRIDGE  COLLAPSES" is 8 cm on the original

Let us use the ratio method to find the length of the headline on the enlarged copy

→  Enlarged  :  Original

→  5               :  4

→  x               :  8

By using cross multiplication

∵ x × 4 = 5 × 8

∴ 4 x = 40

Divide both sides by 4

∴ x = 10

∵ x represents the headline on the enlarge copy

∴ The length of the headline on the enlarge copy is 10 cm
