Using Real World Percent to Solve a Problem

The video tutorial explains how to solve a math problem involving percentages and fractions. A student starts with 500 milliliters of water, drinks 25% before soccer practice, and then drinks 1/3 of the remaining water after practice. The tutorial demonstrates how to calculate the amount of water left using mental math, resulting in 250 milliliters remaining.

Explain how you would calculate 25% of 500 milliliters.

How much water did the student drink before soccer practice?

What was the total amount of water left in the bottle after the student drank 125 milliliters?

How much water did the student drink after soccer practice?

What is the total amount of water left in the bottle after both drinking sessions?
