14 multiplied by 5 is 70. So he will need 14 telephone poles.

Answer:

to understand this we will turn 5 5/6 into a inproper fraction 5 can be turned into 60/12 and 5/6 can be turned into 10/12 so this is equal to 70/12.

5 5/6=70/12

in 70 there are 14 pairs of 5's, 14x5=70

this means that he will need 14 telephone pole's
