Answer 1

Answer:He has enough paints to make the orange paint

Step-by-step explanation:

The key to answering this question is to share the 750ml into the ratio given.

Afterwards, what we do is to check if what we have shared is equal to the volumes we have at hand. Then from here, we can conclude if we have enough volumes or not.

Total ratio is 5+ 4 + 1 = 10

For the red paint we have

5/10 * 750 = 375 ml

For the yellow, we have

4/10 * 750 = 300ml

For the white paint, we have

1/10 * 750 = 75ml

Now since the ratio we have shared does not at any point exceed the stock level of the paints she has, we can conclude that he has enough paints to make the orange paint
