Question

A species of bacteria is antibiotic resistant. Out of 300 bacteria, 210 reproduce with this mutation. What percentage of the resistant bacteria successfully reproduced? answer in percent

Answer 1

210/300 = 70%
100% - 70% = 30% successful

Answer 2

Antibiotics are chemicals and medicines that can impede the growth and infection of the bacteria in other organisms by killing or attenuating them.  

70% of the bacteria are successfully reproduced resistant bacteria.

The resistance can be explained and determined as:

When the bacteria develop immunity and resistance against the use of antibiotics designed for killing them are called resistance towards the antibiotics.

Given,

• Total number of bacteria = 300

• Bacteria with mutation and antibiotic resistance = 210

• Percentage of resistant bacteria:

$\begin{aligned} & = \dfrac {210}{300}\times 100\\\\&= 70\%\end{aligned}$

Therefore, 70% of the bacteria are antibiotic-resistant.
