The Basics of Percentages

Before we delve into the topic of “80 percent of 70,” let’s discuss the basics of percentages. A percentage is a way to express a number as a fraction of 100. For example, 50% is the same as 50/100 or 0.5. Percentages are used in various fields, including finance, science, and mathematics.

What Does “80 Percent of 70” Mean?

When we say “80 percent of 70,” we are asking what number is 80% of 70. To find the answer, we can use the following formula:

Therefore, 80 percent of 70 is 56.

Why Is This Calculation Important?

The calculation of “80 percent of 70” may seem trivial, but it has practical applications. For instance, if you are shopping during a sale where items are discounted by 80%, you can quickly calculate the sale price of an item that originally costs $70. The sale price would be $14 (i.e., 80% of $70).

The Relationship Between Percentages and Fractions

For example, if the price of a stock increases from $50 to $60, the percentage increase would be:

To calculate percentage decrease, the formula is the same, except that you subtract the new value from the old value:

Percentage decrease = [(old value – new value)/old value] x 100
