Answer:
2/5 , 3/7 , 4/9, 3/5
Step-by-step explanation:
One way of approaching this problem is to convert all four fractions to their approximate decimal forms:
0.600, 0.400, 0.429, 0.444
It's immediately obvious that 0.400 is the least of them and 0.600 the greatest. In order by least to greatest, we get:
0.400, 0.429, 0.444, 0.600, or, returning to the original formats,
2/5 , 3/7 , 4/9, 3/5
