for the first one just multiply 3 x 5 x 6 x 2 to get the total number of outfits

number 2 is easy too it gives us the total length so you have to add the ratios 2:5 for the total relationship 2+5=7 21/7=3 so just mutiply 3 by 2 since it is asking for the smaller part so the small is 6 in and the larger part is 15 inches

when given a ratio, add the two parts, 2:5 to get the "total" 7 divide that into the actual total 21, to get 3 then multiply 3 by 2 and 5 to get 6:15
