In September 8 out of 10 days were rainy. how many total days in September were rainy

24 days were rainy

Step-by-step explanation:

8 out of 10 days were rainy ... meaning 2 out of 10 days were not rainy

so the ratio of rainy days to not rainy days is : 8:2 ... added = 10

so 8/10 of all the days are rainy and 2/10 of all the days are not rainy.

there are 30 days in september ...

8/10 of 30 are rainy ... 8/10 * 30 = 240/10 = 24 rainy days <===

2/10 of 30 are not rainy ... 2/10 * 30 = 60/10 = 6 non rainy days

wouldnt it be 18

Step-by-step explanation:

because 8+10=18.-.
