Answer:
1 : 4
Step-by-step explanation:
A scale is a diagrammatic representation of a real-size object on paper.
Let's look at the question again:
height of man in the photograph = 6 ft
height of man on paper = 1.5 inch
scale will be: 1.5 inch to 6 ft
but we want the scale in the lowest terms, so
1.5 : 6
dividing by 1.5 gives
so the scale will be 1 : 4
In other words, 1 inch on paper will be 4 ft in real life.
