Question

Maggie surveyed the sixth graders at her school and found that for every three students who can whistle, there are five students who can't whistle. How many students in Maggie's school can whistle?

1) 15
2) 18
3) 20
4) 25

Answer 1

There are 7 students in Maggie's school who can whistle.

Step-by-step explanation:

Let's assume that for every three students who can whistle, there are five students who can't whistle. We can use this information to set up a ratio:

1. Three students who can whistle : Five students who can't whistle

We can simplify this ratio by dividing both sides by 3:

1. 1 student who can whistle : 5/3 students who can't whistle

We know that there are 35 students in total according to your mom's count. To find out how many students can whistle, we can set up a proportion:

1. 1/5 : x/35

Cross-multiply and solve for x:

1. 35 * 1 = 5x
2. x = 35/5
3. x = 7

Therefore, there are 7 students in Maggie's school who can whistle.
