To determine which set of numbers is arranged in ascending order, we need to compare the values in each option. Let's convert them to decimal form where necessary:
A. 0.000325, 0.00225, 0.00125, 0.00325
- 0.000325
- 0.00125
- 0.00225
- 0.00325 (Ascending order: 0.000325, 0.00125, 0.00225, 0.00325)
B. 0.00125, 0.00225, 0.000325, 0.00325
- 0.00125 (will come after some values)
- 0.00225 (will come after some values)
- 0.000325 (this is the smallest)
- 0.00325 (Not in ascending order)
C. 3.25 × 10^−4, 1.25 × 10^−3, 2.25 × 10^−3, 3.25 × 10^−3
- 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)
D. 3.25 × 10^−3, 2.25 × 10^−3, 3.25 × 10^−4, 1.25 × 10^−3
- 3.25 × 10^−3 = 0.00325 (is the largest)
- 2.25 × 10^−3 = 0.00225
- 3.25 × 10^−4 = 0.000325
- 1.25 × 10^−3 = 0.00125 (Not in ascending order)
After analyzing all options, A and C are ordered correctly in ascending order. However, C clearly shows the increasing order of magnitude in scientific notation.
Thus, the options that contain the numbers in ascending order are:
- A: 0.000325, 0.00125, 0.00225, 0.00325
- C: 3.25 × 10^−4, 1.25 × 10^−3, 2.25 × 10^−3, 3.25 × 10^−3
Since both A and C are correct, you can select either based on the format you'd prefer.
