Question

Sahar lives in a city where the ratio of sunny days to rainy days is 4 to 3. How many rainy days will there be if there are 17 sunny days?

​

Answer 1

13 rainy days

Explanation:

Let's say

• The number of sunny days is x
• The number of rainy days is y.

We know that the ratio of sunny days to rainy days is 4 to 3, so we can write the following proportion:

x:y = 4:3

We also know that there are 17 sunny days.

So, we can substitute x with 17 in the proportion above.

This gives us:

17:y=4:3

We can written this as:

`\tt (17)/(y)=(4)/(3)`

To solve for y, we need to cross-multiply. This gives us:

4y=17*3

`\tt y=(17*3)/(4)`

y= 12.75

Since days are not calculated in fraction,so

y=13

Therefore, there will be 13 rainy days in the city.
