Questions & Step-by-Step Solutions
If a man can complete a task in 12 hours, how much of the task can he complete in 3 hours?
Step 1: Understand that the man can complete the entire task in 12 hours.
Step 2: Determine how much of the task he can complete in 1 hour. This is done by dividing 1 (the whole task) by 12 (the total hours). So, 1/12 of the task is completed in 1 hour.
Step 3: Now, calculate how much he can complete in 3 hours. Multiply the amount completed in 1 hour (1/12) by 3. So, (1/12) * 3 = 3/12.
Step 4: Simplify 3/12. This can be simplified to 1/4. Therefore, in 3 hours, he can complete 1/4 of the task.
