Question

the size of a red blood cell is 0.000007 m and the size of a plant cell is 0.00001275 m find ratio of the size of the plant cell to that of the red blood cell​

Answer 1

Answer:

7*10power-6 is the correct answer

Answer 2

We can write size of a red blood cell 0.000007 as :-

$\dfrac{7}{1000000}$

and plant cell 0.00001275 as :-

$\dfrac{1275}{100000000}$

So,ratio of the size of plant cell to the red blood cell is

$\dfrac{1275}{100000000} \div\dfrac{7}{1000000}$

$\dfrac{100000000}{1275} \times\dfrac{7}{1000000}$

$\dfrac{100}{1275}\times 7$

$\dfrac{700}{1275}$

$\dfrac{28}{51}$

Therefore,ratio of the size of the plant cell to that of the red blood cell​ is 28:51
