Totsakan enlarged the size of a photo to a

height of 18 in. What is the new width if it

was originally 2 in tall and 1 in wide?

The width of the enlarged photo is 9 inches.

Given:

Original length = 2 inches

Original width = 1 inch

Extended length = 18 inches

Extended width = ?

2:1 = 18:x

2x = 1*18

2x = 18

2x/2 = 18/2

x = 9 * extended width.

to check:

2:1 = 18:9

2*9 = 1*18

18 = 18
