Flexi answers - What is 20 percent of 300? (2024)

Flexi Says:

Apercent is a ratio that describes a quantity out of 100. A percent is also a part of a whole. Finding the percent of a number is the part of a number that is equivalent to the percent.

Steps to find the percentage of a number - Method 1

Let's, find 20% of 300 using proportion.

First, write the percent as a fraction. 20% is also 20 out of 100.

@$$\begin{align*}20\%=\frac{20}{100}\end{align*}@$$

Next, write a proportion to find the equivalent fraction of 20% of 300. The second fraction is the unknown quantity, represented by@$\begin{align*}x\end{align*}@$, over the whole, 300.

@$$\begin{align*}\frac{20}{100}=\frac{x}{300}\end{align*}@$$

Now, cross-multiply to find the cross-product. To cross-multiply, multiply thenumerator of one fraction with the denominator of the other fraction. The products should be equal.

@$$\begin{align*}20(300)=100x\end{align*}@$$

Finally, simplify the equation to solve for @$\begin{align*}x\end{align*}@$. Multiply 20 by 300 and divide both sides by 100.

@$$\begin{align*}20(300)&=100x\\[6pt]\frac{6000}{100}&=\frac{100x}{100}\\[6pt]60&=x\end{align*}@$$

Hence, 20% of 300 is 60.

Steps to find the percentage of a number - Method 2

Another method is to use keywords and multiplication. Let's look again at the problem.

What is 20% of 300?

First, look for keywords that suggest an operation. The word "of" tells you to multiply 300 by 20%.

Next, convert 20% to a decimal.

@$$\begin{align*}20\%=0.2\end{align*}@$$

Then, write an equation to find the unknown number, @$\begin{align*}x\end{align*}@$.

@$$\begin{align*}x=300\times 0.2\end{align*}@$$

Finally, solve for @$\begin{align*}x\end{align*}@$ by multiplying 300 by 0.2.

@$$\begin{align*}x=300\times 0.2=60\end{align*}@$$ The answer is the same. 20% of 300 is 60.

Steps to find the percentage of a number - Method 3

The relationship@$\begin{align*}\text{percent} = \frac{\text{part}}{\text{whole}}\end{align*}@$ can be used to solve for a percent using the part and the whole. By multiplying the whole by the other side you get the following equation:@$$\begin{align*}\text{percent} \cdot \text{whole}= \text{part}\end{align*}@$$

Step 1: Divide the percentage by 100.

Step 2: Multiply the result by the number you want to find the percentage of.

For example, find 20% of 300.

Part = ?

Whole = 300.

Percent = @$\begin{align*}20\% \rightarrow \frac{20}{100}.\end{align*}@$

@$$\begin{align*}\text{Percent} \cdot \text{Whole}& = \text{Part} \\\frac{20}{100} \cdot 300 & = \text{Part} \\60 & = \text{Part}\end{align*}@$$

∴ 20% of 300 is 60.
