Are you struggling with calculating percentages? Do you want to know what is 70 of 20? If yes, then you have come to the right place. In this article, we will discuss how to calculate percentages and specifically focus on 70 of 20.
What is a percentage?
A percentage is a way of expressing a fraction or a ratio as a fraction of 100. It is generally denoted by the symbol %, and it is used to represent a part of a whole. For example, if you have a pizza with 8 slices and you eat 2 slices, then you have eaten 25% of the pizza.
Understanding 70 of 20
When we say 70 of 20, we are essentially asking what percentage 70 is of 20. In other words, we want to know how much of 20 is represented by 70. To calculate this, we use the following formula:
70% of 20 = (70/100) x 20 = 14
So, 70 of 20 is 14. This means that 70% of 20 is 14.
How to calculate percentages
Calculating percentages is a simple process. To calculate a percentage, you need to divide the part by the whole and multiply the result by 100. The formula for calculating a percentage is as follows:
Percentage = (Part/Whole) x 100
Let’s take an example to understand this better. Suppose you have a bag with 20 marbles, out of which 5 are blue. To calculate the percentage of blue marbles, we will use the above formula:
Percentage of blue marbles = (5/20) x 100 = 25%
So, 25% of the marbles in the bag are blue.
