luckily, all of the denominators are factors of 100.
rainy: 12/100

Answer 2

Answer:

(c) 60% of the days were sunny or rainy.

(d) 40% of the days were cloudy or partly cloudy.

Step-by-step explanation:

We have been given a pie chart, which represent weather during September.

(c). To find the percent of the days that are sunny or rainy, we will add sunny days to rainy days and then convert them into percent as:

$\text{Days that are sunny or rainy}=\frac{4}{25}+\frac{11}{25}$

$\text{Days that are sunny or rainy}=\frac{4+11}{25}$

$\text{Days that are sunny or rainy}=\frac{15}{25}$

$\text{Percent of the days that are sunny or rainy}=\frac{15}{25}\times 100$

$\text{Percent of the days that are sunny or rainy}=15\times 4$

$\text{Percent of the days that are sunny or rainy}=60$

Therefore, 60% of the days were sunny or rainy.

(d). To find the percent of the days that are cloudy or partly cloudy, we will add cloudy days to partly cloudy days and then convert them into percent as:

$\text{Days that are cloudy or partly cloudy}=\frac{1}{10}+\frac{3}{10}$

$\text{Days that are cloudy or partly cloudy}=\frac{1+3}{10}$

$\text{Days that are cloudy or partly cloudy}=\frac{4}{10}$

$\text{Percent of the days that are cloudy or partly cloudy}=\frac{4}{10}\times 100$

$\text{Percent of the days that are cloudy or partly cloudy}=4\times 10$

$\text{Percent of the days that are cloudy or partly cloudy}=40$

Therefore, 40% of the days were cloudy or partly cloudy.
