You have learned how to add and subtract fractions as well as mixed numbers. These skills are useful in your everyday life when you are cooking, traveling, and shopping. Addition and subtraction are just two of the basic mathematical operations. The others, multiplication and division, can also be applied to fractions. Watch the video below to see how you can use the multiplication of fractions in your life.
Let's Watch
Chef Fractiona is a well-known chef. She makes meals, desserts, and hors d’oeuvres for people to enjoy!
Today she needs to create a special fruit punch to serve with a baked dessert for guests at a math competition.
The recipe Chef Fractiona has for fruit punch will make 12 gallons, but she needs to make only half of that amount.
This means that Chef Fractiona will need to multiply the amount of each ingredient in the recipe by one-half.
Multiplying fractions is part of Chef Fractiona’s everyday life in her kitchen.
You’ve multiplied fractions in your life, too. Maybe, like Chef Fractiona, you needed to reduce a recipe. Or perhaps you needed to make sure you had enough fabric to make new curtains. Maybe you’ve even used fraction multiplication to split a bill at a restaurant.
In this lesson, you will practice multiplying fractions using a few strategies. These strategies will help you master your fraction multiplication skills, just as Chef Fractiona has mastered the art of cooking!
Question
"of"
In a word problem, the word “of” usually means that you should multiply. For example, saying "\( \frac{2}{3} \text{ of } \frac{2}{7} \)" means \( \frac{2}{3} \times \frac{2}{7} \).
