A student has a container with a volume of 1.5 liters. She estimates the volume to be 1.2 liters. By what percent is the student's estimate off?

The student's estimate is 20% off.

Step-by-step explanation:

Given that a student has a container with a volume of 1.5 liters, so

As the student estimates the volume to be 1.2 liters, so

Therefore,

Percentage Error = [ |Approx Value - Exact value| ] / [ | Exact value |] × 100

                              = | 1.2 - 1.5 | / | 1.5 |  × 100

                              = [ 0.3 / 1.5 ] × 100

                              = 0.2 × 100

                              = 20%

Therefore, the student's estimate is 20% off.
