Question

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

Answer 1

there will be 14 of them
Because if you would turn the fractions into a decimals 1/4 would be 0.25, and 7/8 would be 0.875, so now you divide 12.25 and 0.875 and you would get 14
(i think if i'm wrong sorry)

Answer 2

There are 14 speed limit signs on the highway

Explanation:

We can solve this questions by unitary methods.

∵ At every
`(7)/(8)` kilometers number of speed limit signs = 1

∴ At every 1 kilometer number of speed limit signs =
`(1)/((7)/(8))` or
`(8)/(7)`

∴ Then on a highway having length
`12(1)/(4)` km or
`(49)/(4)` km number of speed limit signs =
`(8)/(7)* (49)/(4)`

= 14 speed limit signs

Therefore, there will be 14 speed limit signs on the highway.
