Vinh has a recipe for a marinade. The recipe says to mix ⅜ cup olive oil, ¼ cup of soy sauce, and ⅛ cup lime juice. How much olive oil does he need to make 9 cups of the marinade?

1. Multiply 3/8 by 9 to get how many cups of olive oil you will need for 9 cups of marinade.
2. Once you multiply 3/8 by 9 you will get 27/8 which is an equivalent to 3.375 cups of olive oil or if you were rounding to the nearest tenth it would be 3.4 cups of olive oil.
