Least to greatest 4 1/4, 4 1/8, 5 10/11, 4 2/12

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 ...)
