Question

Three are three petri dishes in a laboratory. The first one contains 22.340 cells, the second contains 43.560 cells, and the last dish contains 36.612 cells. Approimately how many cells are there in total?

100,000

1,000,000

10,000

150,000

Answer 1

To find the total number of cells in the three petri dishes, we can sum the number of cells in each dish:

1. First dish: 22,340 cells
2. Second dish: 43,560 cells
3. Third dish: 36,612 cells

Now, let's add them together:

\[
22,340 + 43,560 + 36,612 = 102,512
\]

Now we can determine which of the options is closest to this total:

- 100,000
- 1,000,000
- 10,000
- 150,000

The closest option is **100,000**.
