Mr. Bowen has a black-and-white picture of a frog that he'd like to reduce in size for a worksheet he's creating for his biology class. The picture is currently 16 centimeters long and 12 centimeters wide. If he wants to reduce the length to 2 inches, what must be the reduced width to maintain proportionality of the picture?

1.5 inches

diyadiya · Answer

To maintain proportionality
$$Length:width=New \ Length :New \ Width$$

Given:
Length = 16
Width   =12 
New Length = 2
New Width = x 

$$\frac{16}{12}= \frac{2}{x}$$
Can you find  x now ?
