Write two expressions that could be used to find 80% of x. Please help

A percent is always out of 100, so 80% can also be thought as 80 out of 100. Theres multiple ways of writing this ratio like in fraction and decimal form. Here are two ways you can write the expression.

Fraction Form:
80/100 • x

Decimal Form:
.80 • x

The fraction form shows that there is 80 out of 100, consequently the next expression shows that ratio in decimal form with 80 in the hundredths place.

The two expressions that could be used to find 80% of x are: [tex]\frac{80x}{100}[/tex] and [tex]0.8x[/tex]

In this exercise, you're required to write two (2) mathematical expressions to find 80% of x. This simply means that you will represent the variable x in terms of 80%.

Note: 80% = [tex]\frac{80}{100} = 0.8[/tex]

First expression;

We would write this mathematical expression in terms of 100 as a fraction.

[tex]\frac{80}{100}[/tex] × [tex]X[/tex]

Simplifying further, we have;

[tex]\frac{80X}{100}[/tex]

Second expression;

We would write this mathematical expression as a decimal.

[tex]0.8[/tex] × X

[tex]0.8x[/tex]

Therefore, the two (2) mathematical expressions are [tex]\frac{80x}{100}[/tex] and [tex]0.8x[/tex]
