Fractions:
How We Use Them in the Real World
There were
many times I sat in math class asking myself, when am I going to need this in life?
Why do I need to learn this stuff? As I’ve come to learn, math is an essential
skill that I use every day, for example yesterday, when I decided I wanted to
make cookies for an employee party.
The wind was
fiercely blowing, and the air was brisk, it was the perfect day to stay in the
house and bake some warm, chewy chocolate chip cookies. The recipe that I
followed is posted below: https://www.verybestbaking.com/recipes/18476/original-nestle-toll-house-chocolate-chip-cookies/
2 1/4 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon salt
1 cup (2 sticks) butter, softened
3/4 cup granulated sugar
3/4 cup packed brown sugar
1 teaspoon vanilla extract
2 large eggs
2 cups (12-oz. pkg.) NESTLÉ® TOLL HOUSE® Semi-Sweet
Chocolate Morsels
1 cup chopped nuts (optional)
*The first thing I did was
preheat my oven to 375 degrees
*The next
step was to mix the flour, baking soda, and salt into a bowl, but I decided I
wanted to double my recipe, and this is where my knowledge of fractions is
required. In order to double my recipe each ingredient in the recipe will need
to be doubled
*The first
ingredient the recipe calls for is 2 ¼ cups of flower.
2 ¼ x 2 =
2 ¼ x 2/1=
The first fraction we focus on is the 2 ¼
The 4 is multiplied by the 2 too equal 6, and then add the
numerator (1) too equal 7, the original numerator will stay the same in the end
result, which would be 7/4.
The 7/4 is then multiplied by the 2/1 straight
across
7/4 x 2/1 = 14/4, we end up with an improper fraction that
needs to be changed back into a mixed number, to do this we need to divide.
14 goes into 4, 3 times, the 2 is carried, and the 4
becomes the denominator. The end result looks like this, 3 2/4
*I followed these same steps to figure out how much of each
ingredient I needed in order to double my cookie recipe.
*I mixed my sugars, vanilla, and butter in another bowl.
The eggs were then added one by one, next the flower was mixed in. The final
step is to add the chocolate chips.
*Put your cookies in the oven, and wait to enjoy!
This recipe makes 5 dozen cookies before doubling it! If you plan to double this recipe, I hope you
have a lot of friends to share with!
