The original height of a digital photograph measures 350 pixels. The new height of the photograph measures 613 pixels. By what percentage has this photo been enlarged?
Correct Answer:
175%
Explanation:
When a photo is enlarged, you can express the new size as a percentage of the original by dividing the new dimension by the original and multiplying by 100. So compute 613 divided by 350, which is about 1.7514. Multiply by 100 to get roughly 175.14%, meaning the new height is about 175% of the original height. Rounding gives 175%. Note the distinction: this is the final size as a percentage of the original. If you were asked for the percent increase, you’d subtract 100%, yielding about a 75% increase (since 613 is about 1.75 times the original).
