The percent of the bacteria on the petri dish is from colony 3 is 18.3%.
<h3>What is percentage?</h3>
A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.
Let assume that the total number of bacterias in all the dishes is 1200 and the number of bacteria in colony 3 is 220.
The percentage will be:
= Number from colony 3 / Total number × 100
= 220/1200 × 100
= 18.3%
Note that the figures were assumed as the information is incomplete.
