So we can first convert the percentages to decimals. This means we would turn 60% into 0.6. So we have 0.2, 0.6, and 0.75. We know that 0.75 is the closest to 1, so it is the largest, 0.6 is the second closest, so it is the second largest, and 0.2 is the farthest, so it is the smallest. Therefore the order is:
1st: 0.75
2nd: 60%
3rd: 0.2.
Hope this helps. :D Feel free to ask more questions or ask about my explanation.
