there are three Petri dishes in the laboratory the first one contains 22,340 cells, the second contains 43,560 cells, and the last dish contains 36, 612 cells. Apporoximately how many cells are there in total.

Question

A. 150,000
B. 1,000,000
C. 100,00
D. 10,000

Answer 1

To approximate the total number of cells, we can round each given number to the nearest thousand and then add them up.

22,340 rounded to the nearest thousand is 22,000.
43,560 rounded to the nearest thousand is 44,000.
36,612 rounded to the nearest thousand is 37,000.

Adding these rounded numbers together:
22,000 + 44,000 + 37,000 = 103,000

Therefore, the approximate total number of cells is 103,000, which is not one of the answer choices given.
