Answer:

7 telephone poles

Step-by-step explanation:

Given that:

Length of track = 5(3/5) feet long

No pole is needed at the atart of the track

Poles are however placed every 4/5 foot apart

Number of telephone poles needed :

Length of track / distance between each placed poles

= length of track = 5(3/5) = 28/5 feet

Distance between poles = 4/5 foot

Hence,

(28 /5) ÷ (4 /5)

= 28 /5 × 5 / 4

= (28 * 5) / 20

= 140 / 20

= 7

Number of poles required = 7

Step-by-step explanation:

5 5/6 / 5/12

Keep Change Flip

35/6 * 12/5

cross simplify

7/1 * 2/1= 14/1= 14
