Question

The size of the red blood cells is 0.000007 m & size of the plant cell is 0.00001275 m. What is the approximate ratio of their sizes?

Answer 1

HERE.....
The Fraction will be.....
$\frac{0.000007m}{0.00001275m} \\ = \frac{0.000007m}{0.00001275m} \times \frac{ {10}^{8} }{ {10}^{8} } \: \: \: \: \: \: {{(since \: there \: are \:upto \: 8 \: decimals \: in \: the \: denominator)}} \\ = \frac{700}{1275} \\ = \frac{28}{51}$
THEREFORE, The RATIO = 28 : 51....

THERE YOU GO!!!

Answer 2

Step-by-step explanation:

The size red blood cells =0.000007m

The size of plant cell=0.00001275m

Ratio= 0.000007m/0.00001275m

=7/1000000×100000000/1275

=700/1257

=140/255

=28/51

Therefore the ratio is 28:51
