Changing from a percent to a decimal is best learned by seeing an example.
40.5% = .405 as a decimal
57.63% = .5763 as a decimal Look at these problems and try to guess how percents are converted to decimals answer
Changing 37 1/2% to a decimal can be done in two ways.
1. Convert 1/2 to .5 and replace the 1/2 in the problem so we know have
37.5% Then we follow the above procedure and the answer is .375.
2. Sometimes we need to use the following method.
23 1/8% Change this to an improper fraction 185/8 %. Don't forget the % sign. Now remove the % sign and replace it with /100. So the problem looks like
185/8/100 which means 185/8 ÷ 100 which changes to 185/8 x 1/100 and your answer is 185/800 This reduces by dividing numerator and denominator 5. Your answer will be 37/160 = .23125
