If a person can complete a task in 12 hours, how much of the task can they complete in 3 hours?

Step 1: Understand that the person can complete the entire task in 12 hours.
Step 2: Determine how much of the task is completed in 1 hour by dividing 1 (the whole task) by 12 (the total hours). This gives us 1/12 of the task per hour.
Step 3: Multiply the amount completed in 1 hour (1/12) by the number of hours worked (3 hours). This is 1/12 * 3.
Step 4: Calculate 1/12 * 3, which equals 3/12.
Step 5: Simplify 3/12 to 1/4. This means the person completes 1/4 of the task in 3 hours.
