Fractions and mixed numbers are often used in everyday life. Discuss a real-life example in which you would need to add, subtract, multiply, or divide fractions or mixed numbers, and show the math to get maximum quality points.
Thank you for the opportunity to help you with your question!
A great example is when preparing food while using a recipe:
Recipe requires 1 cup of uncooked rice - rice expands 3 fold during cooking. If I have 2 1/2 cups of cooked rice, I will need to know how much uncooked rice to add to get the appropriate amount. I would need to divide the volume of the cooked rice by 3.
2 1/2 divided by 3 = (5/2) / (3/1) = (5/6). I have (5/6) cup of uncooked rice, subtract that from 1. 1-(5/6) = (1/6) so I need 1/6th of a cup of uncooked rice to complete the recipe :).
Please let me know if you need any clarification. I'm always happy to answer your questions.
