Real-life Examples of Multiplication
Real-life Examples of Multiplication
Understanding multiplication is easier when we connect it to real-life situations. Here are some examples that help demonstrate the practical uses of multiplication in everyday life.
Shopping and Budgeting
When shopping, you often buy several items of the same type. If each apple costs $2 and you buy 5 apples, you can use multiplication to find the total cost:
let pricePerApple = 2;
let numberOfApples = 5;
let totalCost = pricePerApple * numberOfApples;
console.log(totalCost); // Outputs: 10
In this case, multiplication helps calculate that 5 apples cost $10 in total.
Cooking and Recipes
Recipes often require adjusting based on the number of people to be served. If a recipe calls for 3 cups of flour to serve 4 people, but you need to serve 12 people, you multiply to adjust the ingredients:
let cupsOfFlourForFour = 3;
let peopleToServe = 12;
let factor = peopleToServe / 4;
let cupsOfFlourForTwelve = cupsOfFlourForFour * factor;
console.log(cupsOfFlourForTwelve); // Outputs: 9
This calculation shows that you'd need 9 cups of flour to serve 12 people.
Travel and Time Management
Travel plans often require calculating time. If a car travels at 60 miles per hour and you plan to travel for 3 hours, you multiply to find the total distance:
let speed = 60; // miles per hour
let time = 3; // hours
let distance = speed * time;
console.log(distance); // Outputs: 180
The multiplication reveals that the car will travel 180 miles in 3 hours.
Array and Rows in Organizing
When organizing objects, such as arranging chairs for an event, you often use multiplication. If there are 10 rows with 8 chairs in each row, you multiply to find the total number of chairs:
let chairsPerRow = 8;
let numberOfRows = 10;
let totalChairs = chairsPerRow * numberOfRows;
console.log(totalChairs); // Outputs: 80
This computation indicates there are 80 chairs in total.
