Question 532080
Ms. Niemeyer is taking the train 3,240 miles to Oregon.
 She will travel 1/8 the distance the first day and 1/6 the distance on the second day.
 How far will she have left to go after two days? 
:
Let d = remaining distance after two days
:
d = 3240 - {{{1/8}}}(3240) - {{{1/6}}}(3240)
Both of these fraction will cancel into 3240, so you have
d = 3240 - 405 - 540
d = 2295 mi to go
