Question

The robots will be taking over 1/3 of the normal work. You have hired four robots. How much of the total work will they each be doing?

Answer 1

they all as a group will be doing 1/3 of the work. There are 4 robots.

how much will each individual robot will be doing from the total work?

well, how many times does 4 go into 1/3?


`\bf \cfrac{\quad (1)/(3)\quad }{4}\implies \cfrac{\quad (1)/(3)\quad }{(4)/(1)}\implies \cfrac{1}{3}\cdot \cfrac{1}{4}\implies \cfrac{1}{12}\\\\ -------------------------------\\\\ \stackrel{first~robot}{\cfrac{1}{12}}+\stackrel{second~robot}{\cfrac{1}{12}}+\stackrel{third~robot}{\cfrac{1}{12}}+\stackrel{fourth~robot}{\cfrac{1}{12}}\implies \cfrac{4}{12}\implies \stackrel{\stackrel{total}{work}}{\cfrac{1}{3}}`
