the size of a red blood cell is 0.000007m and the size of plant is0.00001276 compare these two.. this question answer is 1/2 but how?
Divide.
0.000007 / 0.00001276
To compare the sizes of the two objects, we need to find the ratio of their sizes. Let's compare the size of the plant to the size of the red blood cell.
Size of red blood cell: 0.000007 m
Size of plant: 0.00001276 m
To find the ratio, we can divide the size of the plant by the size of the red blood cell:
Ratio = Size of plant / Size of red blood cell
= 0.00001276 m / 0.000007 m
To simplify the ratio, we can divide both the numerator and the denominator by the common factor of 0.000007:
Ratio = (0.00001276 m / 0.000007 m) / (0.000007 m / 0.000007 m)
= 0.00001276 m / 0.000007 m
= 1.8228571
Therefore, the ratio of the size of the plant to the size of the red blood cell is approximately 1.8228571.
It seems there was a mistake in the original question. The ratio is not 1/2, but rather around 1.82.
To compare the sizes of a red blood cell and a plant, we need to calculate the ratio of their sizes.
The size of a red blood cell is given as 0.000007 m, and the size of a plant is given as 0.00001276 m. To compare these two, we can divide the size of the red blood cell by the size of the plant:
Size of red blood cell / Size of plant = 0.000007 m / 0.00001276 m
Now, to simplify this fraction, we can find a common factor to divide both the numerator and denominator. In this case, we can divide by 0.000000001:
(0.000007 m / 0.000000001) / (0.00001276 m / 0.000000001)
Simplifying further:
7 / 1 / 12.76 / 1
Now, we divide 7 by 12.76:
7 ÷ 12.76 ≈ 0.548
So, the ratio of the sizes of the red blood cell to the plant is approximately 0.548.
However, the information given doesn't state that the ratio is exactly 1/2. It is possible that there was some rounding or approximation made in the calculation, which resulted in the answer being stated as 1/2.
