Thank you sir ❤

[@steveabney1954]

Set up all percentage problems this way:
Part/whole = %/100 = is/of
You must know 2 of these three (part, whole, % -- 100 is constant.)
What is 25% of 80? (we don't know the part)
x/80 = 25/100
x = (80*25)/100 = 2000/100 = 20
40 is what percent of 160? (we don't know the %)
40/160 = x/100
x = (40*100)/160 = 4000/160 = 25%
36 is 75% of what? (we don't know the whole)
36/x = 75/100
x = (36*100)/75
x = 48

Thank you it's much easier this way when solving small numbers without having to use calculator
