Question

Scaling up a 4 inch by 6 inch image by 50% results in which of the following image size

Answer 1

50% or 1/2 of 4 is 2 50% or 1/2 of 6 is 3 so then just add them to the respective number since its going up by 50% or 2 in by 3 in \[\frac{ 6 }{ 9}\]

Answer 2

The size of the image is 4 inch by 6 inch

Size of the image scale up by 50%

4 in increased by 50 % = New length = x

$\frac{x}{4}=\frac{50}{100}$

Cross multiply, we get

100 x = 4(50)

100x = 200

Divide both side by 100, to find x

x = 200/100

x = 2

New length = original length + increased length

New length = 4 + 2 = 6 in

6 in increased by 50 % = New length = y

$\frac{y}{6}=\frac{50}{100}$

Cross multiply, we get

100 y = 6(50)

100y = 300

Divide both side by 100, to find y

y = 300/100

y= 3

New length = original length + increased length

New length = 6 + 3 = 9 in

So New dimensions are 6 in by 9 in
