Oh boy. Set up a proportion, as in 20% is the same as 20/100
20/100 = x/450
Do you see how the x relates to the 20? x will be 20% of 450.
Cross multiply.

$450 = 100% ( ÷ 100).
$4∙50 = 1% ( x 20).
$90 = 20%.

$90 is correct. The easiest way to figure out 20% in your head, is to multiply the number by 2 and move the decimal point one space to the left.
It helps in figuring out tips. Let's say you went to a restaurant and spent $450, and wanted to leave a 15% tip, you would figure that 15% would be half way between 10% and 20%, so it would be half way between $45 and $90, which would be $67.50.

lets 1st change 20% into a whole number.we will divide 20 to 100.
20/100=0.2
multiply 0.2 to 450.
450(0.2)=90
answer:90 dollars
