Answer:
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 [tex]\frac{5}{4}[/tex] 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
