Question from Kenneth: What does the following indicate? "A percent is another way of expressing the ratio or fractional relationship I know what a ratio is, but the term "fractional relationship" confuses me. I thank you for your reply. |
Hi Kenneth,
Suppose I have $\$10$ and you have $\$25$ then the fractional relationship of what I have to what you have is $\frac{10}{25}.$ You probably wouldn't leave the fraction in that form but divide the numerator and denominator by 5 to get the equivalent fraction $\frac25.$ In other works I have two-fifths of what you have. But you could just as easily multiplied the numerator and denominator of $\frac{10}{25}$ by 4 to obtain the equivalent fraction $\frac{40}{100}.$ But this is a percent, "per one-hundred". Thus I have $40\%$ of what you have.
