In which set are the numbers arranged in ascending order?

To determine which set of numbers is arranged in ascending order, we first convert all numbers to decimal form:

1. Set 1:

   • \(3.25 \times 10^{-4} = 0.000325\)
   • \(1.25 \times 10^{-3} = 0.00125\)
   • \(2.25 \times 10^{-3} = 0.00225\)
   • \(3.25 \times 10^{-3} = 0.00325\)
   • In ascending order: \(0.000325, 0.00125, 0.00225, 0.00325\)

2. Set 2:

   • \(0.000325\)
   • \(0.00125\)
   • \(0.00225\)
   • \(0.00325\)
   • In ascending order: This set is correctly ordered.

3. Set 3:

   • \(0.00125\)
   • \(0.00225\)
   • \(0.000325\)
   • \(0.00325\)
   • Not in ascending order.

4. Set 4:

   • \(3.25 \times 10^{-3} = 0.00325\)
   • \(2.25 \times 10^{-3} = 0.00225\)
   • \(3.25 \times 10^{-4} = 0.000325\)
   • \(1.25 \times 10^{-3} = 0.00125\)
   • Not in ascending order.

From this analysis, the sets arranged in ascending order are the first and second sets:

1. 1st Set: \(0.000325, 0.00125, 0.00225, 0.00325\)
2. 2nd Set: \(0.000325, 0.00125, 0.00225, 0.00325\)

Thus, both the 1st and 2nd responses are in ascending order.
