One out of every five people who buys ice cream buy vanilla ice cream. If a store sells 125 ice cream cones in one day, about how many will be vanilla?

I know how to solve the proportion once I set it up, but I cant figure out how to set it up

1/5 = x/125

x=25

25

To set up a proportion, we need to establish the relationship between the number of vanilla ice cream cones sold and the total number of ice cream cones sold.

Let's use the information given: one out of every five people who buy ice cream choose vanilla. This means that for every 5 ice cream cones sold, one of them will be vanilla.

We can use this ratio to set up a proportion:

Vanilla ice cream cones sold / Total ice cream cones sold = 1 / 5

We can represent the total ice cream cones sold as "125" since the question states that the store sells 125 ice cream cones in one day.

Vanilla ice cream cones sold / 125 = 1 / 5

Now we need to solve for the unknown value, which is the number of vanilla ice cream cones sold.

To do that, we can cross-multiply and then solve for the unknown:

Vanilla ice cream cones sold = (1 * 125) / 5
Vanilla ice cream cones sold = 125 / 5
Vanilla ice cream cones sold = 25

Therefore, approximately 25 out of the 125 ice cream cones sold in one day will be vanilla.
