A robot can complete 4 tasks in 5/6 hour. Each task takes the same amount of time. a. How long does it take the robot to complete one task? b. How many tasks can the robot complete in one hour? a. It takes the robot nothing hour(s) to complete one task.

Here's what we know:

4t = 7/10 (4 tasks take 7/10 of an hour)

Divide both sides by 4:

4t / 4 = 7/10 / 4

t = 7/40

So each task is 7/40 of an hour

7/40 n = 1 (Now we want to find the number of tasks completed in 1 hour)

Multiply both sides by 40/7:

n = 40/7

Converting improper fraction to a mixed number:

n = 5 5/7

So the robot will complete 5 5/7 tasks in an hour. If the answer is looking for fully finished tasks and not partially done ones, the you need to round down to 5.
