Total length of the road = 6 3/4 miles.
Each markers are spaced at a distance = 1/8 of a mile.
Number of markers could be represented by following division problem:
Total length of the road ÷ each marker space =
a) 6 3/4 ÷ 1/8.
b) In order to solve it, we need to convert that fraction into improper fraction:
6 3/4 = 27/4
6 3/4 ÷ 1/8 = 27/4 ÷ 1/8
We need to convert division sign into multiplication sign and flip the second fraction.
27/4 × 8/1
On simplifying, we get
27 × 2 = 54.
c) There would be total number of 54 markers of lengths (1/8) of a mile.
