1. Fractions are important because they tell you what portion of a whole you need, have, or want. Fractions are used in baking to tell how much of an ingredient to use. Fractions are used in telling time; each minute is a fraction of the hour.

2. 5 situations where can we use fraction:

  1. Eating at a Restaurant: Think about a time you go to a restaurant with friends and the waitress brings a single bill. To divide the total amongst the friends, you use fractions.
  2. Shopping: Think about the time you went shopping for a new school bag. There was half off on everything due to a sale, so you calculate the new price using fractions.
  3. Following a Recipe: Recipes sometimes suggest using 1/2 a teaspoon of sugar, 3/4 tablespoon of salt. Some recipes also have quantities to serve 2. If we are making the same dish to serve 3 people, fractions are used to adjust the ingredients accordingly.
  4. Sports: Fractions are frequently used to analyze the performance of a particular player and team.
  5. Fitness: We use fractions to understand our body mass index (BMI) to determine whether we are in a healthy range of body mass or not.
