A robot can complete 4 tasks in 7/10 of an hour. each task takes the same amount of time. how many tasks can the robot complete in one hour

Answer 1

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.
