The time it takes the population of a micro organism to reduce by half is 0.000027503 of a year. What number is the best estimation of this quantity would it be 0.00003 or would it be 0.00002 or 0.03 or 0.0 one.

Answer 1

To determine which number best estimates 0.000027503 of a year, we can compare it to the options provided:

- 0.00003
- 0.00002
- 0.03
- 0.01

The given number, 0.000027503, is closest to 0.00003.

To clarify:
- 0.00003 (which is equal to 0.000030) is slightly larger than 0.000027503.
- 0.00002 is smaller than 0.000027503.
- 0.03 and 0.01 are much larger than 0.000027503.

Thus, the best estimation of 0.000027503 of a year is **0.00003**.
