Marneshia walked three over eight of a mile in three over five of an hour. What equation can be used to calculate her unit rate in miles per hour?
3/8 over 3/5 = 5/8 mile per hour
3/8 over 3/5 = 1 and 3/5 miles per hour
3/5 over 3/8 = 1 and 3/5 miles per hour
3/5 over 3/8= 5/8 mile per hour

you do 3/8*5/3
Mehek (mehek14):
because
3/8 / 3/5 = 3/8= 5/3 = 5/8
OpenStudy (anonymous):
you get 15/24 then you must reduce
OpenStudy (anonymous):
to get A
Mehek (mehek14):
