Final answer:
The correct answer to the ratio of the length of cell A to cell B is option B (6:0.00000003). To compare, we convert to the same units and calculate, resulting in a simplified ratio.
Step-by-step explanation:
The correct answer is option B. To determine the ratio of cell A's length to cell B's length, we first convert the given lengths to the same unit if they are different.
Given that the length of cell A is 6 times the length of cell B, we can represent this ratio as A:B = 6:1.
To simplify this ratio, we divide both sides by the common factor of 2, resulting in A:B = 3:1.
Therefore, the ratio of cell A's length is 10 units to the ratio of cell B's length, which is 3 units, giving us the final ratio of A:B = 10:3.
Cell A has a length of 6×10, which is 60. Cell B has a length of 0.00000003 meters. To find the ratio, we place the length of cell A over the length of cell B, obtaining 60:0.00000003. Simplified, the ratio is 6:0.00000003 because the common factor of 10 is canceled in the ratio.
