A tv has height ratio 3:4. In a scale drawing the height is 4.5cm what would the width be?

Answers

4.5 ÷ 3 = 1.5
This means that the ratio has increased by 1.5

Since anything multiplied on one side of a ratio has to be multiplied on the other side too, we multiply 1.5 by 4: 
1.5 X 4 = 6

The width would be 6cm
