a. 3:1
b. 1:3
c. 7:21
d. 21:7

Answer 1

The ratio of wet days to dry days is 3:1, calculated by dividing the number of wet days (21) by dry days (7).

Step-by-step explanation:

The ratio of wet days to dry days is calculated by dividing the number of wet days by the number of dry days. In this case, there are 21 days with rain (wet days) and 7 days without rain (dry days). The ratio is therefore 21 wet days to 7 dry days, which simplifies to 3:1 when both numbers are divided by 7. Hence, the correct answer is a. 3:1.
