 Math Central Quandaries & Queries
 Question from aryanna, a student: i need to find out how to find percentage on a calculator??the equation is $19.54,, is 20 % off????? Hi Aryanna, I think you have an extra f and the question should be$19.54 is 20 % of ?????

This is almost a "mathematical sentence", that is an equation. The word "is" could be "is equal to" which is the equal sign, 20% is 20/100 = 0.20 and "of" means multiplication. So the sentence can be rewritten

$19.54 = 0.20 × ????? Dividing both sides by 0.20 gives ????? =$19.95/0.20 = \$97.85
