Answer:
part 1) It takes 2/15 hour to complete 1 task
Part 2) The robot can only complete 7 tasks in an hour (the remaining doens’t count)
Step-by-step explanation:
So first divide to find unit rate
2/5 ÷ 3
2/5 * 1/3
2/15
For part 2
Just put the unit rate in an equation
2/15x=1
Where 1 is the single hour and x is the task
solve
you’ll get 7 1/2
Due to only requesting for tasks in an Hour
its only 7 task
Try shutting of things that could distract you. (Television, phone, computer etc.)
Get away from noise; go somewhere quiet.
You would have to do: 682+117=799
Then you do: 799-45=754
Last you would do: 754+130=884 .
