A casting, when first poured, is 14.872 inches long. The casting shrinks 0.098 inch when it cools. What is the percent of shrinkage is round to two decimal places?

Answer 1

To find the percentage of shrinkage, we divide the shrinkage by the original length and then multiply by 100.

Shrinkage = 0.098 inches
Original length = 14.872 inches

Percentage of shrinkage = (Shrinkage / Original length) * 100

Percentage of shrinkage = (0.098 / 14.872) * 100

Percentage of shrinkage ≈ 0.659 * 100

Percentage of shrinkage ≈ 65.9%

Therefore, the percent of shrinkage is approximately 65.9% when rounded to two decimal places.
