Question

Sam must inspect 11/14 of a mile of high voltage line. He has already inspected 3/14 of a mile. How much additional line must he​ inspect?

Answer 1

Subtract the part, which is done, from the whole:

`x = (11)/(14) - (3)/(14) \\ \\ x = (8)/(14) = (4)/(7)`

Answer 2

Hey!

Sam has to inspect a total of 11/14 of a mile. He has already inspected 3/14 of a mile. Subtract the amount he has to inspect by how much he already has done.

`(11)/(14) - (3)/(14) = (8)/(14) = (4)/(7)`

`\framebox{Answer = 4/7 of a mile of high voltage line}`
