I want to use this equation:
[ miles / hour ] / [ miles / gallon ] = [ gallons / hour ]
then I want to use:
[ gallons / hour ] x [ hours ] = [ gallons ]
---------------------------------------------
[ miles / hour ] / [ miles / gallon ] = [ gallons / hour ]
+%28%28+130%2F4+%29%29+%2F+%28%28+117%2F3+%29%29+=+%28+130+%2F+4+%29%2A%28+3+%2F+117+%29+
+390+%2F+468++=+65+%2F+78+
and
[ gallons / hour ] x [ hours ] = [ gallons ]
+%28+65+%2F+78+%29%2A6+=+390+%2F+78+
+390+%2F+78+=+5+
5 gallons will be consumed
