Transforming the Fraction 718.5/100 to a Percentage

Q: Why can I just use the numerator as the percentage?

Because percent means "per hundred"! When you have a fraction with 100 in the denominator, you're already expressing "parts per hundred," which is exactly what percentages represent.

Q: What if the numerator is a decimal like 718.5?

Decimal numerators are perfectly fine! $ \frac{718.5}{100} $ still equals 718.5%. Percentages can be whole numbers, decimals, or even greater than 100%.

Q: How do I know if a percentage greater than 100% makes sense?

Percentages over 100% mean more than the whole. For example, 718.5% means 7.185 times the original amount, which is perfectly valid in many real situations!

Q: Is there a difference between 718.5% and 71.85%?

Yes, huge difference! 718.5% = 7.185 as a decimal, while 71.85% = 0.7185 as a decimal. The decimal point placement in percentages matters enormously.

Q: Can I convert this to a mixed number instead?

You could write $ \frac{718.5}{100} $ as $ 7\frac{18.5}{100} $, but the question asks for a percentage, so 718.5% is the correct answer format.
