Percents Less Than 1%

Be careful with percents less than 1%.
Handle them the same way (move exactly
2 places).
    Example: 0.3% = 0.003
Recall: To change a percent to a
decimal, move the decimal point two places
to the left (because percent means divided by
100)
  Change each to a decimal:
  1. .1%
                              .1% .001
  2. .08%
                              .08% .0008
  3. 0.24%

                              0.24% .0024
Recall: To change a percent to a fraction,
change to a decimal and then read it to make
it a fraction.
  Change each to a fraction:
  1. .1%                             1
                         .1% .001
                                   1000
  2. .08%                    8    2     1
              .08% .0008
                           10000 2500 1250
  3. 0.24%
                                       24      3
                       0.24% .0024
                                     10000   1250
Examples:
1. If the price of a share of RST    .13
   stock started the day at                 .002443 0.24%
                                    53.20
   $53.20 and went up $0.13,
   what is the percent increase?

2. If the human body had 10 pints of blood and .08% of
   the blood is alcohol (the legal level of
   intoxication), how much alcohol is in the blood?
                                   .0008*10 .008 pints

2. If Joseph has $2,000,000 invested and 0.5% is
   invested in Dell Computers, how much is invested in
   Dell Computers?
              .5% of 2,000,000 .005 2,000,000 $10,000
