A student has a container with a volume of 1.5 liters. She estimates the volume to be 2.1 liters. By what percent is the student's estimate off?(Round to the nearest percent as needed.)

40 percent

Step-by-step explanation: real value = 1.5 liters ,estimated value = 2.1 liters.

Percentage student's estimate = (difference in estimate/ real value) × 100

Difference in estimate = 2.1-1.5 = 0.6

Real value = 1.5

Percentage student's estimate = (0.6/1.5)×100 = 0.4×100 = 40 percent
