4% x $45 = 4/100 x $45 = .04 x $45 = $1.80
There is a calculator in your "accessories" (click Start, Programs, Accessories, Calculator)
You can also type an equation like a question in the Search window of Google and it will give you an answer, but it does not show the work.

Here's a trick that will help you from now on.
In math, the word "of" means "times."
For example, 10% of 20 means 10% times 20, or
0.10 * 20. The answer is 2!
In your case, the answer is 0.04 * 45, or 1.8.
You can also use this trick in more complex problems. For example:
20 is what percent of 200?
Translate that to......
20 = ____% * 200
Use a letter to represent the blank percentage (just for fun)...
20 = y * 200,
Divide both sides by 200....
20/200 = (y * 200)/200
Then simplify....
0.10 = y
y = 10%

Convert the percentage into a decimal and change "of" to multiplication:
(0.04) x ($45) = $1.80

1. change the percentage to a decimal by dividing by 100
(per cent = for every hundred)
2. multiply the decimal by 45
(of = multiply)
