3/2 = 1.5
4.5/3 = ?
4.5/3 = ?
Let's first find the scaling factor that needs to be applied to the original picture.
Original Picture Dimensions: 2 inches (width) by 3 inches (height)
Enlarged Picture Dimensions: 3 inches (width) by 4.5 inches (height)
To find the scaling factor for width:
Scaling Factor (Width) = Enlarged Picture Width / Original Picture Width
Scaling Factor (Width) = 3 inches / 2 inches
Scaling Factor (Width) = 1.5
To find the scaling factor for height:
Scaling Factor (Height) = Enlarged Picture Height / Original Picture Height
Scaling Factor (Height) = 4.5 inches / 3 inches
Scaling Factor (Height) = 1.5
Since both scaling factors are the same (1.5), we can conclude that Jake needs to use an enlargement setting of 1.5 on the copy machine.
