Final answer:
The question involves ordering sets of numbers from least to greatest. Percentages are converted to decimals for comparison, resulting in ordered sets {0.6, 0.70}, {0.17, 0.8}, and {0.615, 0.65} respectively.
Step-by-step explanation:
The student's question involves ordering each set of numbers from least to greatest. It is important to first convert all values into the same format to compare them easily. We will convert percentages into decimal form to compare them with other decimal values. For example, 70% becomes 0.70, and 17% becomes 0.17.
For the first set {70%, 0.6}, we convert 70% to 0.70 and then compare it to 0.6. The ordered set from least to greatest is {0.6, 0.70}.
The second set is {0.8, 17%}. Converting 17% to a decimal gives us 0.17. The ordered set from least to greatest is {0.17, 0.8}.
For the third set {0.65, 61.5%}, converting 61.5% to decimal form gives us 0.615. The ordered set from least to greatest is {0.615, 0.65}.
