How many ounces are there in a normal bottle (750ml) of wine? Set up proportion………….. 1000 ml 750 ml = 33.8 oz X oz Cross products 1000(x) = 33.8 (750) 1000(x) = 25350 Rule of algebra. (Divide both sides by 1000 to isolate X 25.35 ounces. 2. How many ounces are there in a “pocket rocket” or airline bottle of 50ml? 1000 ml 50 ml = 33.8 oz X oz Cross products 1000(x) = 33.8 (50) 1000(x) = 16.90 Rule of algebra. (Divide both sides by 1000 to isolate X 1.69 ounces. 3. How many cups in a gallon? 16 Look at chart. Many different proportions you can set up to solve. 4. How many grams in an ounce? 2.2 pounds equals 35.2 oz I think some of you thought the (point) 2 was ounces? Don’t know- look at your work! 1 pound 2.2 pounds = 16 oz X oz Cross products 1(x) = 16(2.2) X = 35.2 2 1000 grams x grams = 35.2 oz 1 oz Cross products 1000(1) = 35.2 (x) 1000 = 35.2 (x) Rule of algebra. (Divide both sides by 35.2 to isolate X 28.40909091 = x 5. 5.25 kilograms equals how many pounds? See above Answer is 11.55 pounds 6. A recipe calls for 430 ml of white wine. How many cups would you need to use? 1000 ml 430ml = 33.8 oz X oz Cross products is 14534 = 1000(X) Rule of algebra – divide both sides by 1000 14.534 oz = X Now how many cups is this? Set up proportion…………….. 1 cup X cups = 8 oz 14.534 oz Cross products, isolate x,,,,,, 1.81675 cups. 7. If a bottle of wine costs you $7.00 how much each 7oz glass cost you? (Figure that if you have any “extra” it will be used for the next full glass.) Do not round your answer! 1000 ml 750 ml = 33.8 oz 1 oz We solved that there are 25.35 oz in this bottle. $7.00 X $ = 25.35oz 7 oz 7(7) = 25.35(X)
