The Basics of Percentages
When we talk about percentages, we're talking about parts of a whole. A percentage is a way of expressing a number as a fraction of 100. For example, if we say that 50% of a group of people is male, we mean that 50 out of every 100 people are male. Percentages are used in a variety of situations, from calculating discounts to measuring success rates.Understanding Fractions
To understand percentages, we must first understand fractions. A fraction is a way of expressing a part of a whole. It's written as a numerator over a denominator, separated by a line. For example, 3/4 means that we have 3 parts out of a total of 4 parts. Fractions can be converted into percentages by multiplying them by 100. For example, 3/4 x 100 = 75%, which means that 75 out of every 100 parts are represented by the fraction 3/4.Now that we understand the basics of percentages and fractions, let's apply this knowledge to the question "what is 5 of 1000?"
Calculating 5 of 1000
To calculate 5 of 1000, we need to convert the fraction 5/1000 into a percentage. To do this, we can multiply the fraction by 100.5/1000 x 100 = 0.5%
So, 5 of 1000 is 0.5%. This means that 5 out of every 1000 parts are represented by 0.5%.Real-Life Applications of Percentages
Now that we understand how to calculate percentages, let's take a look at some real-life applications of percentages.Discounts
Discounts are often expressed as percentages. For example, if a store is offering a 10% discount on a product that costs $100, we can calculate the discount by multiplying the price by the percentage.10% of $100 = $10
So, the discount is $10, and the new price of the product is $90.Interest Rates
Interest rates are also expressed as percentages. For example, if a bank is offering an interest rate of 2% on a savings account, we can calculate the interest earned by multiplying the balance by the interest rate.$1000 x 2% = $20
So, the interest earned is $20.
