Answer: 30%
Step-by-step explanation: Reading through the problem we have <em>24 is</em>, that's <em>24 equals</em>, <em>what percent</em> means <em>x/100</em>, <em>of 80</em>, means times 80.
Notice that I put <em>x/100</em> for <em>what percent</em> since percent means <u>over</u> <u>100</u>.
Cross-canceling the 80 and 100 to 4 and 5, we have 24 = 4x/5.
Multiplying both sides by 5 to get rid of the fraction, we have 120 = 4x.
Now dividing both sides by 4, we find that <em>30 = x</em>.
Remember the problem is asking for <em>what percent</em> so we should write our answer as 30% to answer the question.
