To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100. In this case, 84% can be written as the ratio 84 to 100 or [tex]\frac{84}{100}[/tex]. Notice however that [tex]\frac{84}{100}[/tex] is not in lowest terms. So, we need to divide the numerator and the denominator by 4 which gives us [tex]\frac{21}{25}[/tex].
Therefore, 84% can be written as the fraction [tex]\frac{21}{25}[/tex], which is in lowest terms.
