First off, 1/5 is equal to 20%. If you're diving something into 5ths, you can do 100 / 5, which is 20. So you know that Raul scored at least 20% of the points. His friend Jake ALSO scores 20% of the teams points, making 20 + 20 = 40%. Therefore, 40% of the teams points were scored by Raul and Jake.
(1/2) / 15 = x / 50......1/2 in. to 15 miles = x inches to 50 miles cross multiply because this is a proportion (15)(x) = (50)(1/2) 15x = 25 x = 25/15 x = 5/3 or 1 2/3 inches <==
