The ratio of students who prefer pineapple to students who prefer kiwi is 12 to 5. Which pair of equivalent ratios could be used
AlexFokin [52]

Answer:

<u> 105</u> students could prefer kiwi if there are 357 total students.

Step-by-step explanation:

Given:

The ratio of students who prefer pineapple to students who prefer kiwi is 12 to 5.

Now, to find number of students prefer kiwi if there are 357 total students.

Let the students prefer pineapple be 12x.

And the students prefer kiwi be 5x.

Total students = 357.

So, we set an equation to get the number of students who prefer kiwi.

According to question:

12x+5x=357

17x=357

<em>Dividing both sides by 17 we get:</em>

x=21.

<em>Thus, students prefer kiwi are:</em>

5x

=5\times 21=105.

Therefore, 105 students could prefer kiwi if there are 357 total students.
