:) Hope you do great on it!
the ratio of zinc to copper is 3 to 14, that menas that for each 3 grams of zinc there are 14 grams of copper, so we can made a rule of three to find
9.4 - 6 = 3.4
12.8 - 9.4 = 3.4
16.2 -12.8 = 3.4
hence the difference between the terms is common and = 3.4
1/5 of 55 is 11, you multiply 11 by 20 and you get 220. Total there is 1100 minutes of tv so then you subtract 220 from 1100 and there is 880 minutes of tv without commercials then you divide that by 60 and you get 14 hours and 20 minutes.
