Firs you need to convert the mixed numbers to decimals (left to right): 4.25; 4.125; 5.909091; 4.166667.. Then you organize them from least to greatest: the 4 as the whole number comes first, adding from the greater place values later; and then the 5 as it's the biggest number.. which makes the order:: 4.125, 4.166667,4.25, 5.909091.. (sorry if explained the way of how kind of bad.. I'm not very good at explanations, but I know my math..)
