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
