Finding the total amount given the percentage of a partial amount.

In a recent year, 23.3% of all registered doctors were female. If there were 57,700 female registered doctors that year, what was the total number of registered doctors?

Round your answer to the nearest whole number.



Answer :

To determine the total number of registered doctors given that 23.3% of them were female and that there were 57,700 female registered doctors, we can proceed with the following steps:

1. Understand the relationship:
[tex]\[ \text{Percentage of Female Doctors} = \frac{\text{Number of Female Doctors}}{\text{Total Number of Doctors}} \times 100 \][/tex]

2. Substitute the known values:
Given that 23.3% of the doctors are female and there are 57,700 female doctors, we can write:
[tex]\[ 23.3 = \frac{57700}{\text{Total Number of Doctors}} \times 100 \][/tex]

3. Rearrange the equation to solve for the total number of doctors:
[tex]\[ \text{Total Number of Doctors} = \frac{57700}{\frac{23.3}{100}} \][/tex]

4. Simplify the fraction:
First, compute the percentage as a decimal:
[tex]\[ \frac{23.3}{100} = 0.233 \][/tex]
Then, divide the number of female doctors by this decimal:
[tex]\[ \text{Total Number of Doctors} = \frac{57700}{0.233} \][/tex]

5. Perform the division:
[tex]\[ \frac{57700}{0.233} \approx 247639.14 \][/tex]

6. Round to the nearest whole number:
The total number of registered doctors rounded to the nearest whole number is approximately:
[tex]\[ 247639 \][/tex]

Therefore, the total number of registered doctors was approximately 247,639.
