Question

A new road was added near Riana's neighborhood. The road is 5 miles long and the city plans to place a street light every 1/10 mile. There already is a streetlight at the beginning of the new road. How many streetlights will be placed on the new road

Answer 1

5*the denominator of the fraction 10, since there are 10 1/10 in one, so they will use that many lights, then you get 50. After that, we take 50, and subtract it by 1, since a street light is already there, to get 49.
