Answer :
Final answer:
When a 1:2 ratio is given, it means for every 1 part of the first substance, there should be 2 parts of the second. Option B, 3 oz color to 6 oz developer, is correct as it adheres to this ratio.
Explanation:
When directions specify a 1:2 ratio, this means for every 1 part of the first substance, you should mix in 2 parts of the second substance. In the context of mixing color and developer for hair products or similar applications, you want to ensure you have double the amount of developer compared to the color if the ratio is 1:2. Therefore, the correct mixing from the provided options would be B. 3 oz color to 6 oz developer, as this maintains the specified 1:2 ratio with 3 ounces being half of 6 ounces.
