Answer 1

28 because the number of spots in the pathway where the lampposts will be placed is 1/5 divided by 3/10=14. since each spot will have 2 lampposts, there will be 14*2=28 lampposts in all.

hope this helped!!!!!!!!!!!!!!!!!!!!!!!!

Answer 2

14

Explanation:

Distance of the pathway around a park = 4 1/5 miles

Distances between lamppost = 3/20 miles

Numbers of 3/10 intervals

= 4 1/5 ÷ 3/10

= 21/5 x 10/3

= 14

Number of lamp posts = 14
