Does anyone know how to to order these fractions from least to greatest

Turn the fractions into percents:
#11: 3/9= 3 divided by 9
           = 0.33 x 100
           = 33%

1/4= 1 divided by 4
    = 0.25 x 100
    = 25%

5/12= 5 divided by 12
      = 0.42 x 100
      = 42%

LEAST TO GREATEST: 1/4,3/9, and 5/12

#13: 1/2= 1 divided by 2
            = 0.5 x 100
            = 50%

7/12= 7 divided by 12
         = 0.58 x 100
         = 58%

4/10= 4 divided by 10
         = 0.4 x 100
         = 40%

LEAST TO GREATEST: 4/10, 1/2, and 7/12
