You can put this solution on YOUR website!
In terms of just units:
( miles ) / ( miles/gallons ) = gallons
+100+%2F+%28+270+%2F+15+%29+=+100%2A%28+15%2F270+%29+
+1500+%2F+270+=+5.556+ gallons
----------------
check:
+100+%2F+%28+270+%2F+15+%29+=+5.556+
+100+=+5.556%2A%28+270%2F15+%29+
+100+=+5.556+%2A+18+
+100+=+100.008+
close enough
OK
