3 % can be expressed 3/100 (always view % meaning 1/100, so 3% becomes 3/100)
let x be your unknown
x = 3% x 500 pounds
x = 3/100 x 500 pounds
x=1500 pounds / 100
x = 15 pounds
as you get proficient with percentages, you can drop the equation and just do the math on the right hand side of the equation. But sometimes to arrange your thoughts, it does not hurt to lay it out on paper.
Another approach to work out percentages in your head
first divide the amount by 100 (which is easy to do),
500 pounds by 100 = 5 pounds
then multiply by 3 = 15 pounds
why divide by 100? because % = 1/100
