The percent (percentage) of a given number p/q can be found, for the most part, without a calculator by a slight change in the notation:
y=the number 29/36 expressed as a percent becomes
y=[29(2.7777777778 approx.)]/[36(2.7777777778 approx.)]
y=0.8055 approx. (Express the decimal numeral as a percent)
y=0.8055(100)
y=
80.55% approx., which is 80.6% rounded up to the nearest tenth percent
