Question

An electrician needs 6 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 3/62 of a roll of wire?

Answer 1

Use a rule of three to find the amount of rooms wire with 3/62 rolls:

`x=((3)/(62)rolls*1room)/(6rolls)=((3)/(62))/(6)rooms=(3)/(6*62)rooms=(3)/(372)rooms=(1)/(124)rooms`

Then, with 3/62 of a roll can be wire 1/124 parts of a room
