Transcript of Copy of Ratios and Proportions Recipe project

Ratios and Proportions Recipe Project by: Cathy Mae C. Dutong Banana Bread! Original recipe (serves 8):
- 1 eggs
- 2 to 3mashed bananas
- 1/3 c of melted butter
- 3/4 c of sugar
- 1 tsp of baking soda
-1 2/3 c of all purpose flour
- 1/2 tsp of cinnamon
- 1/2 tsp of salt
- 1/4 tsp of baking soda
- 1 tbsp of milk If the original recipe uses 3 bananas, and the recipe serves 8, the ratio would be 3/8. If the original recipe uses 1 egg, and the recipe serves 8, then the ratio would be 1/8. my work to solve this problem:
1/8 = x/30 <---- (my proportion)
8x =30x1
8x/8= 30/8
x = 3.75 or 3 3/4 New recipe (serves 30):
- 4 eggs
- 15 bananas
- 1 c of butter
- 1 1/2 c of sugar
- 3 3/4 tsp pf baking soda
- 3 c of flour
- 1 1/4 tsp of cinnamon
- 1 1/3 tsp of salt
- 1 tsp of baking powder
- 3 3/4 tbsp of milk my work to solve this problem:
3/8 = x/30 <---- (my proportion)
8x = 30 x 4
8x/8 = 120/8
x = 15 If the original recipe uses 1/4 cup of butter, the ratio would be (1/4)/8. Steps for making banana bread:
- preheat oven to 350°F (175°C)
- mix sugar and butter in a large bowl
- stir in eggs my work to solve this problem:
(1/4)/8 = x/30 <---- (my proportion)
8x = 30 x 1/4
8x/8 = 7.5x8
x = 0.9375 or 1 If the original recipe uses 3/4 cup of sugar, then the ratio would be (3/4)/8. my work to solve this problem:
(3/4)/8 = x/30 <---- (my proportion)
8x = 30 x 3/4
8x/8 = (11.25)/8
x = 337.5 or 337 1/2 If the original recipe uses 1 teaspoon of baking soda, then the ratio would be 1/8. my work to solve this problem:
1/8 = x/30 <---- (my proportion)
8x = 30 x 1
8x/8 = 30/8
x= 3.75 or3 3/4 If the original recipe uses 1 3/4 cups of flour, then the ratio would be (1 3/4)/8. my work to solve the problem:
(1 3/4)/8 = x/30 <---- (my proportion)
8x = 1 3/4 x 30
8x/8 = 52.5/8
x = 6.5625 If the original recipe uses 1/2 teaspoons of cinnamon, then the ratio would be (1/2)/8. My work to solve this problem
(1/2)/8 = x/30 <---- (my proportion)
8x = 30 x 1/2
8x/8= 15/12
x =1.25 If the original recipe uses 1/2 teaspoons of salt, then the ratio would be (1/2)/8. my work to solve this problem:
(1/2)/8 = x/30 <----(my proportion)
8x = 30 x 1/2
8x/8 = 15/8
x = 1.875 If the original recipe uses 1/4 teaspoons of baking powder, then the ratio would be (1/4)/8 my work to solve this problem:
(1/4)/8 = x/30
8x = 30 x 1/4
8x/8 = (7.5)/8
x= 0.9375 or 1 If the original recipe uses 1 tablespoons of milk, then the ratio would be 1/8. my work to solve this problem:
1/8 = x/30 <--- (my proportion)
8x = 30 x 1
8x/8 = 30/8
x = 3.75 or 3 3/4 Explanation to the math:
To find the amount of ingredients needed for 30 servings, I made the proportion and then cross multiplied it. enjoy! :) - add bananas and milk; beat for 30 seconds
- then add baking soda, flour, cinnamon, salt, and baking powder in a seperate bowl.
-mix all together - evenly distribute into three mini loaf-shaped pans.
- put in oven for 30 minutes
- let it cool for 15 minutes http://www.google.com.bh/url?sa=t&rct=j&q=%20how%20to%20do%20ratios%20and%20proportions%20recipe%20project&source=web&cd=1&cad=rja&sqi=2&ved=0CC4QFjAA&url=http%3A%2F%2Fprezi.com%2Flfdw6tsoilcs%2F&ei=ao3lUIHZNorNtAa99ICwBw&usg=AFQjCNGbKHY3GjCRbMuzc6ZbAalSSN0GMA
