Question

And electrician needs 2 rolls of electrical wire to wire each room in a house how many rooms can he wire with 3/4 of a roll of wire

Answer 1

3/8 room

Explanation:

Given data

We are told that 2 rolls of wire are needed to wire 1 room

Hence if 1 room needs 2 rolls

x rooms will need 3/4 rolls

cross multiply we have

2x= 3/4

Multiply both sides by 1/2

x= 3/4*1/2

x= 3/8 room
