i need to find out how to find percentage on a calculator??the equation is |
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
