Answer:
number of nurses employed at the hospital is 9x = 9 * (7n/9) = 7n, and the number of doctors is 2x = 2 * (7n/9) = (14n/9).
Step-by-step explanation:
Given the ratio of nurses to doctors is 9:2, we can express this as:
Number of nurses (9x) : Number of doctors (2x)
Now, you've mentioned that the total number of nurses and doctors employed at the hospital is 77n. So, we can set up an equation:
9x + 2x = 77n
Combine like terms:
11x = 77n
Now, to find the number of nurses (9x) and the number of doctors (2x), we need to divide both sides by 11:
9x = (77n) / 11
9x = 7n
Now, we can solve for x:
x = (7n) / 9
So, the number of nurses employed at the hospital is 9x = 9 * (7n/9) = 7n, and the number of doctors is 2x = 2 * (7n/9) = (14n/9).
In summary:
- Number of nurses = 7n
- Number of doctors = (14n/9)

Answer:
By using the formula, Parts /whole = percent/100, ⇒ 25/ 50 × 100 = 50%. So, 50 % of 50 is 25 proportion.
