Question
Select the correct answerIn a photo, the width is to the height in a ratio of 4:3. If the height is 9 inches, what is the width?Options9 inches6 inches12 inches16 inches
Solution
The ratio of width to height is given as 4:3. This means for every 4 units of width, there are 3 units of height.
The height is given as 9 inches.
To find the corresponding width, we set up a proportion using the given ratio and the given height:
4/3 = W/9
To solve for W (width), we cross-multiply:
4 * 9 = 3 * W
36 = 3W
Then, divide both sides by 3 to solve for W:
W = 36 / 3
W = 12 inches
So, the width of the photo is 12 inches.
