Question

A stretch of highway 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 of highway?

Answer 1

The length of the highway = 12 1/4 km = 49/4
speed limits signs on every interval length = 7/8 km

number of speed limits = length of highway/speed limits on every interval
number of speed limits = 49/4 ÷ 7/8
number of speed limits = 49/4 × 8/7
number of speed limits = 14

Answer 2

Thank you for asking this question. Here is your answer:

First of all we will multiply 12 by 4 and we will get 48

then we will add 1 to it, that would give up 49

So that means there are 49/8 in the highway

then we will divide 49 by 7

it would give us 7

So that means there are 7 speed limit signs
