To determine which set has the numbers arranged in ascending order, we need to evaluate each option by converting them to decimal form.

Set 1:
0.000325
0.00225
0.00125
0.00325
Decimal forms:- 0.000325 = 0.000325
- 0.00225 = 0.00225
- 0.00125 = 0.00125
- 0.00325 = 0.00325
Ascending order: 0.000325, 0.00125, 0.00225, 0.00325 (NOT in order)
-
Set 2:
0.00125
0.00225
0.000325
0.00325
Decimal forms:- 0.00125 = 0.00125
- 0.00225 = 0.00225
- 0.000325 = 0.000325
- 0.00325 = 0.00325
Ascending order: 0.000325, 0.00125, 0.00225, 0.00325 (NOT in order)

Set 3:
3.25 × 10^−3
2.25 × 10^−3
3.25 × 10^−4
1.25 × 10^−3
Decimal forms:- 3.25 × 10^−3 = 0.00325
- 2.25 × 10^−3 = 0.00225
- 3.25 × 10^−4 = 0.000325
- 1.25 × 10^−3 = 0.00125
Ascending order: 0.000325, 0.00125, 0.00225, 0.00325 (NOT in order)
-
Set 4:
3.25 × 10^−4
1.25 × 10^−3
2.25 × 10^−3
3.25 × 10^−3
Decimal forms:- 3.25 × 10^−4 = 0.000325
- 1.25 × 10^−3 = 0.00125
- 2.25 × 10^−3 = 0.00225
- 3.25 × 10^−3 = 0.00325
Ascending order: 0.000325, 0.00125, 0.00225, 0.00325 (CORRECT)
Thus, the correct set arranged in ascending order is 4. 3.25 × 10−4, 1.25 × 10−3, 2.25 × 10−3, 3.25 × 10−3.
