A Body Lotion Ingredient Calculation
A body lotion is made by mixing coconut milk and olive oil in the ratio of 5 to 4. How much coconut milk and olive oil is required to make 90 ml of the lotion?
Explanation:
To determine the amounts of coconut milk and olive oil needed to make 90 ml of lotion, we'll use the given ratio of 5:4.
First, let's find out how many parts the mixture has in total. The ratio 5:4 means there are 5 parts of coconut milk to 4 parts of olive oil. This makes a total of 5 + 4 = 9 parts.
Next, we need to find out how much one part represents in our desired amount of 90 ml. So, we divide the total amount of lotion by the total parts: 90 ml ÷ 9 parts = 10 ml/part.
Now, for coconut milk, which is 5 parts: 5 parts x 10 ml/part = 50 ml.
For olive oil, which is 4 parts: 4 parts x 10 ml/part = 40 ml.
Therefore, to make 90 ml of the body lotion, you would need 50 ml of coconut milk and 40 ml of olive oil. Thus option C is correct.
A. 60 ml of coconut milk, 30 ml of olive oil B. 30 ml of coconut milk, 60 ml of olive oil C. 50 ml of coconut milk, 40 ml of olive oil D. 40 ml of coconut milk, 50 ml of olive oil 50 ml of coconut milk and 40 ml of olive oil are required to make 90 ml of the lotion. The correct answer is C.
