How do I set up this proportion? It takes Todd 8 minutes to eat 5 pies at a pie eating contest. How many pies can Todd eat in 15 minutes?

\[5/8=x/15\]

How do you set them up though?

OpenStudy (anonymous):

if 8mins=5pies then 15mins=xpies

OpenStudy (anonymous):

this means 8x=15*5

OpenStudy (anonymous):
