Hey there!
In order to find the number that is 33.3% percent less than 24, you would need to convert the percentage into a decimal. To do this, bring the decimal point over two numbers to the left to make it into 0.333. Now, you can multiply that by 24 to find 33.3% of 24.
24 * 0.333 = 7.992 ≈ 8
Now, subtract 8 from 24 to find the answer to your question.
24 – 8 = 16
16 is 33 1/3% less than 24. Hope this helped you out! :-)
