An old picture frame has dimensions 33 inches by 24 inches. What one length must be cut from each dimension so that the ratio of
valkas [14]

Let the length you need to cut = X

The new dimensions would be 33-x and 24-x

The ratio needs to be 2/3

So you have (24-x) / (33-x) = 2/3

Cross multiply:

2(33-x) = 3(24-x)

Simplify:

66 - 2x = 72 - 3x

Add 3x to each side:

66+x = 72

Subtract 66 from both sides:

x = 6

You would need to cut 6 inches off of each dimension.
