Question

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

Answer 1

Answer:

The ratio of their sizes are 28:51

Answer 2

$→ Size \: of \: the \: red \: blood cells = 7 \times {10}^{ - 6}m \\ \ \: → Size \: of \: the \: plant \: cells = 0.00001275m \\→Now, \frac{Size \: of \: blood \: cell} {Size \: of \: plant\: cell } \\ → \frac{7 \times {10}^{ - 6} m}{1.275 \times {10}^{ - 5}m} \\ → (\frac{1}{2} \: or \: 1 : 2)answer$

Hence, a red blood cell is half a plant cell.
