Keisha is right. No, only 1 ratio works

Step-by-step explanation:

You want the units to be dollars / mango. You have 10 dollars. How many mangos can you buy and at what price. They are selling mangoes for more than a dollar each. The answer should be $1.25 per mango. Think of it this way: If the cost of a mango was $1.00 you would be able to get 10 of them. Do you agree? Since you can only get 8, they must be more than a dollar each. The ratio can only be written in one way. 10/8 = 1.25

Answer

Keisha is right. No, only 1 ratio works
