Rainbow [258]

Answer: 60 of the patients are boys.

Step-by-step explanation: According to what is described, 5 in 8 patients are girls, then: 8 - 5 = 3, i.e., 3 in 8 are boys.

Mathematically the proportionality is $\frac{3}{8}$

If 160 patients have appointments per month and $\frac{3}{8}$ are boys:

160. $\frac{3}{8}$ = 60

Per month, 60 boys have appointments at the medical office.
