Question

Caroline bought 8 bananas for $4. What was the cost of the bananas in bananas per
dollar?

Answer 1

2 bananas per dollar

Explanation:

We can represent the correlation between the number of bananas to their cost in a ratio:

bananas : cost

8 : $4

To get the price rate of bananas in bananas per dollar, we can divide both sides of the ratio by 4 so that the cost of the bananas is $1.

bananas : cost

8 / 4 : $4 / 4

2 : $1

This means that the price rate of the bananas is 2 bananas per dollar.

Answer 2

8 bananas for $4, how many bananas is one dollar.

So we will do bananas/price to find out the how many bananas is one dollar.

8 bananas/4 dollars = 2 bananas per dollar.
