Understanding money
Money is a medium of exchange used to buy goods and services. It comes in different denominations – coins and notes. Before we start multiplying and dividing money, let us get acquainted with the basic idea of handling money.
The basics of multiplying money
Multiplying money involves multiplying a monetary amount by a number. This is helpful when you transact multiple quantities of the same item.
Example 1: Buying apples
Imagine you are at a fruit store. Apples cost $2 each and you want to buy 4 apples. How much money will you need?
Cost of 1 apple = $2
Number of apples = 4
Total cost = 2 * 4 = $8Example 2: Buying books
Suppose a book costs $5 and you want to buy 6 books. How much money will you spend?
Cost of 1 book = $5
Number of books = 6
Total cost = 5 * 6 = $30Tips for increasing wealth
- First, multiply the numbers as if there was no decimal point.
- Count the decimal places in the monetary amount and place the decimal point in the result accordingly.
The basics of money division
Splitting money involves dividing a monetary amount into smaller parts or between people. This is common when sharing expenses or calculating unit prices.
Example 1: Sharing a pizza
You and three friends order pizza for $12. How much should each person pay?
Total cost of pizza = $12
Number of people = 4
Cost per person = 12 / 4 = $3Example 2: Calculating unit price
You buy a pack of 10 pens for $15. How much does each pen cost?
Total cost of pens = $15
Number of pens = 10
Cost per pen = 15 / 10 = $1.50Tips for dividing money
- Ensure the accurate placement of the decimal point in the result.
- If a remainder exists, consider rounding or dealing with cents, if applicable.
Important considerations
Always remember to take into account decimal points when making calculations. Decimals are commonly used in money transactions, so accuracy is very important.
