Answer:
The remaining percentage of the bases present in the DNA is equal to 82%
Percentage: it is an important mathematical tool that allows us to establish proportionalities between numbers
The x% of a quantity represents obtaining x from 100 equal parts, therefore to find x% we can divide by 100 and multiply by x, which is equivalent to making a simple and direct rule of three, in the same way if we have a quantity "a" and we want to know how much percent it represents with respect to another "b" then we make a rule of three where "b" would be 100% and we want to determine how much "a" is
So if 18% is Cytosine, then we have that the remaining% is 100%, we remove what is Cytosine, which is then:
100% - 18% = 82%
