How do you find a percentage of an amount without a calculator?

It isn't hard. It's really simple and easy. For example, you want to change 29 into a percentage. One way is this. 29 becomes 29 over 100. 29 over 100 turns into a decimal. You should know decimals. 29 over 100 should be 0.29 hundredths That's how you say the decimal form. 0.29 hundredths becomes 29%. The numerator is the percentage. You really don't need the fraction or decimal. But it helps you understand the procedures.
