Remark
You have to read this carefully to know what way to write it.
One way you could write it would be
20 * x = 18 where x is the fraction. Now all you need do is divide.
Divide both sides by 20
20/20 * x = 18/20

But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.
18: 2 * 3 * 3
20: 2 * 2 *5
Cancel out the Highest common factor or 2.

Answer: $284.80
look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:
1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%
2nd. Next, you do 0.40 x 712.00 = or
712.00
x 0.40

$284.80
2.99 / 14 = 0.21
