The fuel for a chain saw is a mix of oil and gasoline. The ratio of ounces of oil to gallons of gasoline is 5:18. There are 36 gallons of gasoline. How many ounces of oil are there?
16 ounces
10 ounces
129.6 ounces
2.5 ounces
5/18 = x / 36....5 oz oil to 18 gal gas = x oz oil to 36 gal gas cross multiply because this is a proportion (18)(x) = (36)(5) 18x = 180 x = 180/18 x = 10 <=== so there is 10 oz of oil
