Answer :

To solve this problem, we will follow the steps below: 1. **Understand the Percentages:** Newton spends 25% of his free time reading. This tells us that the reading time is a quarter (25 out of 100 parts) of his total free time. 2. **Convert the Percentage to a Fraction:** 25% as a fraction is 25/100, which simplifies to 1/4. 3. **Use the Fraction to Calculate Total Free Time:** Since the reading time of 40 minutes represents 1/4 of his total free time, we can determine his total free time by setting up the equation: `(1/4) * Total Free Time = 40 minutes` To find the total free time, we multiply both sides of the equation by 4: `Total Free Time = 40 minutes * 4` `Total Free Time = 160 minutes` 4. **Convert Minutes to Hours and Minutes:** There are 60 minutes in an hour. We'll divide the total free time in minutes by 60 to find out how many full hours Newton has in his free time: `Hours = 160 minutes / 60 minutes/hour` When we perform this division, we get: `Hours = 2 hours with a remainder of 40 minutes` Newton has 2 full hours of free time, with an additional 40 minutes left over. 5. **State the Final Answer:** Therefore, Newton has a total of 2 hours and 40 minutes of free time.
