A stretch

A stretch of high way that is 12 1/4 kilometers long has speed limit signs every 7/8 of a kilometer. How many speed limit signs are on this stretch highway?

Correct answer:

n =  14/1 = 14

Step-by-step explanation:

s=1241=12+41=412 4+1=449=12.25 km a=7/8=87=0.875 km  n1=s/a=12.25/0.875=14  n=n1=14=14
