What is 70 of 20?
When we talk about “70 of 20,” we’re referring to a percentage. In this case, we’re asking what percentage 70 is of 20. To calculate this, we need to divide 70 by 20 and then multiply the result by 100. This will give us the percentage.
To calculate what percentage 70 is of 20, we can use the following formula: (70 ÷ 20) x 100 = 350% So, 70 is 350% of 20.
Now that we’ve calculated what 70 of 20 means, let’s take a closer look at percentages. A percentage is a way of expressing a fraction or ratio as a portion of 100. For example, if we say that something is 50%, we mean that it is half of 100.
Converting Fractions to Percentages
To convert a fraction to a percentage, we need to multiply the fraction by 100. For example, if we have the fraction 1/4, we can convert it to a percentage by multiplying it by 100: 1/4 x 100 = 25% So, 1/4 is equal to 25%.
Converting Decimals to Percentages
We can also convert decimals to percentages by multiplying the decimal by 100. For example, if we have the decimal 0.75, we can convert it to a percentage by multiplying it by 100: 0.75 x 100 = 75% So, 0.75 is equal to 75%.
Why Percentages are Important
Percentages are important because they allow us to compare different quantities and values. For example, if we’re comparing the profits of two companies, we can express their profits as percentages of their revenue. This allows us to make a fair comparison, even if one company has a higher revenue than the other.
Using Percentages in Business
Percentages are commonly used in business to calculate profits, markups, and discounts. For example, if a company wants to offer a 20% discount on a product that costs $50, they would simply multiply $50 by 0.2 to get the discount amount: $50 x 0.2 = $10 So, the discount would be $10, and the customer would pay $40.
In conclusion, understanding percentages is an important part of basic math. When we talk about “70 of 20,” we’re referring to what percentage 70 is of 20. To calculate this, we divide 70 by 20 and then multiply the result by 100.
