put these four fractions in order from smallest to largest: 1/4, 2/3, 4/7, 1/2

1/4=0.25

2/3= 0.6

4/7=0.57

1/2=0.5

in order from least to greatest 

1/4, 1/2, 4/7, 2/3

1/4    2/3     4/7      1/2

Get a common denominator  between   4, 3, 7  and 2 =    4 * 3 * 7 =  84

So 

1/4  (21 / 21)  = 21/84

2/3 (28 / 28)  =  56/84

4/7 ( 12/12)  =   48/84

1/2  ( 42/ 42)  =  42/84

So....in order  from smallest to largest

21/84     42/84   48/84   56/84  =

  1/4         1/2      4/7         2/3   

To make the simpliest culculation, I made to the conclusion that  1/4=0.25 2/3= 0.6 4/7=0.57  1/2=0.5

Therefore, in order from least to greatest 

1/4, 1/2, 4/7, 2/3
