Step-by-step explanation:

To change from a decimal to a fraction  count the number of decimals and add that many zeros after the 1 in the denominator, then simplify

To change a decimal to a percent, move the decimal to places to the right and add a percent sign

To change a fraction to a decimal divide the numerator by the denominator

To change a percent to a decimal move the decimal 2 places to the left and remove the percent sign( if there are fractions, change to a decimal)

113/1000 =                            .113                                    = 11.3 %

2275/1000 =91/400              .2275                           22 3/4%

1/200                                       .005                                  .5%

3 85/100                                   3.85                                  385%

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9
