Given:

$25.50

Calculate 20%

Solution:

Since we are asked to calculate the value of percentage, we must first change the percentage into decimal. In converting a percentage into decimal, we divide the percentage by 100, hence  in order to convert decimal into percentage, we multiply the decimal by 100. After we have the value of percentage in decimal form, we simply multiply it by $25.50.

=20/100

=0.2

=($25.50)(0.2)

= $5.1

20% of $25.50 is $5.1
