Number of bacteria = 55000
Given:
The length of a bacterium = 1 micrometer
Length of the index finger = 5.5 centimeter
To find:
Number of bacteria can you place end-to-end on the finger?
Solution:
Given length of bacterium = 1 micrometer
Length of the index finger = 5.5 centimeters
To find the number of bacterium convert length of the finger into micrometers
As we know 1 centimeter = 10,000 micrometers
⇒ 5.5 centimeter = 5.5 × 10,000 = 55000 micrometers
No. of bacterium can be fitted in 55000 micrometers of finger
= Length of finger/ Length of bacteria
= 55000 micrometers/ 1 micrometer = 55000
Therefore, Number of bacteria = 55000
