Question

Sara is building a fence that will be 7 miles long when it is completed. Sara has finished building 2/3 of the fence. What is the length of fence (in miles) that Sara still needs to build to complete the fence?

Answer 1

7/3 ft

Explanation:

Given data

Lenght of fence= 7 miles

Amount completed= 2/3 of the total length

let us find the amount completed already = 2/3*7= 14/3 miles

Hence the length of fence remaining for completion is

=7- 14/3

=21-14/3

=7/3

Hence the amount in length undon is 7/3 ft
