The total number of STDs is: 1,945,546
Since that is the total of cases 1,945,546 represents 100%.
To find which percentage of the total is the gonorrhea cases, we need to divide 100 by the total number of cases and multiply the number of gonorrhea cases (the number of gonorrhea cases is 395,216).
So the expression we have to solve is:
First, solve the division:
now, solve the multiplication:
This will be the percentage of the cases of gonorrhea: 20.31%
