Fractions in Action!


Fractions, fractions, everywhere! You can’t seem to get through life without them!
Interview your parents to find out how they use fractions in their lives. When do they add or subtract, multiply or divide fractions. Do they ever use mixed numbers?
Write a brief scenario in your comment to show those fractions in action!

Here’s an example:
I wanted to go to IKEA over the Christmas vacation to pick up some things for the house. I live downtown and it is quite a long way to the airport so I checked how much gas I had before setting out. I had about one quarter of a tank full. When I got to IKEA I realized that I only had one sixth of a tank left. Will I have enough gas to get home or do I need to find a gas station in a hurry?

  1. My brother is building a camera to detect fire.In order to find if the fire is present, he had to see the change of red pixels between two images. He had to find what fraction of change in red pixels had to occur in order to establish if there was really fire in the background. He ran a command, in order to see the number of pixels changed each time. Finally, he took the amount of pixels changed and he divided it by the total number of pixels in the image. He got a result of 1/100 change in pixels.

    When me and my dad watch TV and we have ordered a pizza he gets to eat 5/8 and I eat 3/8.

  3. It was Sunday morning and I was starving. I needed breakfast! I hurried downstairs and saw my mom. I asked her if she could make waffles?She said yes. I asked her what were the ingredients?She said that you need 2 cups of flour, 3 tablespoons of sugar, a teaspoon of vanilla, 2 eggs, and 2 and a half cups of butter. Sooner or later the waffles were ready.

    P.S. My mom uses fractions in cooking!

  4. Dear Mrs Kynigou
    My Mom uses fractions when she makes a cake.
    The ingredients she needs to make the cake are:
    1 and 1/4 cups of water
    1/3 cup vegetable oil
    1/3 of a cup butter
    1 cup of milk
    Finally 3 eggs.
    This is how my mom uses fractions to make a cake.

  5. Dear Ms Kynigou,
    my mom uses fractions when she cuts up a pie. This has happened when we cut up the vasilopita. We had to figure out how many pieces we would have to cut. Then we figured out how to cut the pie.

  6. On New Year’s Eve, my mom had to bake a big vasilopita, which is a traditional Greek cake that is cut for good luck right after the new year comes in at 12 A.M.
    Some of the ingredients which my mom needed to bake the big vasilopita were listed as fractions: 7 eggs; 7 1/2 cups of flour; 3 1/4 cups of sugar; 1 1/2 tsp of soda; 1 1/2 cups of milk; 1 1/4 cups of butter; 1 squeezed lemon; and 1 tsp of orange extract.
    The one thing I can tell you is that mom’s vasilopita was big and delicious! This was one way fractions were used and included in my family’s life!

  7. Dear Mrs. Kynigou,
    One place my parents use fractions in real life is at
    the meat market, where they ask for a specific amount
    of meat in fraction form.
    Your student,

  8. One sunny day my mom decided to make a cake. She went to the grocery store . When she finally got there, she realized, she had forgotten her shopping list. The shopping list explained , the quantity of powdered sugar and other ingredients. She bought 3/6 of powdered sugar. When she came back home ,she realized she needed 6/7 of powdered sugar. Does she have enough powdered sugar for the cake?


    1. Dear Aris,
      Your mom doesn’t have enough powdered sugar.3/6<6/7 so she needs to go buy more sugar.

  9. Dear Mrs. Kynigou,
    My mom said that she used fractions when we cut the Vassilopita at New Year’s day.There were 10 of us plus the piece for Christ and the piece for the house,so we divided the Vassilopita into 12 equal sized pieces.Everybody got 1/12 of the Vassilopita.

  10. Dear Mrs. Kynigou,
    One place my mom uses fractions, is in the supermarket, when she wants to know that the amount of money she has is enough to buy fruits. She wants to buy 2 kg of apples (1 kg costs 1 and 6/10 Euros), 3 kg of bananas (1 kg costs 1 and 4/10 Euros) and 5 kg of oranges (1 kg costs 3/4 Euros). She realized that she only had 10 Euros. Does she have enough money to buy the fruits?
    Your student,

    1. Dear Raneem,
      Your mom doesn’t have enough money because: Oranges cost 3.75 Euros, Bananas cost 4.20 Euros and Apples cost 3.20 Euros. All together they cost 10.95 Euros. She needs 95 Cents more.
      I think your comment was smart because of the math that we had to do.

  11. Dear Mrs. Kynigou,

    This morning my mom was preparing a recipe for clay in her sculpture studio. She needed to fill a container with 11 19/43 kg. of porcelain. Luckily she found a 12 kg. bag of porcelain in her storage space. My foxy little brother Ody had stolen 350 gr. out of the bag. Now my mom had to figure out if she had enough porcelain to fill the container. If she had, how much would she have left over?


  12. Dear Mrs. Kynigou,
    My father uses fractions when he has to place different items on shelves. He has to see how he is going to fit different sized things on the shelves. For instance, he needed to put 20 large, 35 medium and 60 small sized bottles on a shelf. He needed different amount of space for the bottles. He could not just split the shelf into thirds because the sizes and amount of bottles were different which made it harder. That day he split the bottles into fifths: 1/5 for the large, 1/5 for the medium and 3/5 for the small ones.

  13. Dear Mrs. Kynigou,
    When my mom was making a cake she needed 1 1/2 tea cup of sugar. She have only 8/9 of a jar equal to 4 cups. Will she have enough sugar to make a cake?

  14. Tarry was on a tight time schedule.He was really on a tight time schedule. At exactly 2:52 was when he got off the school bus. The moment he stepped on to the ground he ran home. He must be ready by and ready I mean changed into his soccer uniform by at 2:55, he doesn’t want to be late for soccer.then his friend Tom comes to pick him up. It is a twenty minute ride to get to the soccer fields. Soccer takes 45 mins. As a fraction, how many hours does in take Tarry the minute he steps off the school bus to the end of soccer practice?
