Answer 1

25

Explanation:

This is how you solve these types of ratio problems.

The ratio of students wearing sandals to sneakers is 5:1.

For example, there could be 5 students wearing sandals and 1 student wearing sneakers. The total then is 5 + 1 = 6.

This is much less than 30, so let's try again by keeping the ratio 5:1 but multiplying both sides by 2.

There could be 10 students wearing sandals and 2 students wearing sneakers. Now the total is 10 + 2 = 12. This is still much less than a total of 30.

Since we don't know what number we need to multiply both 5 and 1 in the ratio by to get a total of 30, let's call that number x.

There are 5x students wearing sandals to 1x students wearing sneakers.

The ratio is

5x : x

When we add the two numbers in the ratio, we must get 30.

5x + x = 30

Solve for x.

6x = 30

x = 5

Now that we know x = 5, and the ratio is 5x sandals to x sneakers, then the number of students wearing sandals is

5x = 5(5) = 25
