How to fix a mixture to make a specific shade of green glaze when it is made of 5 parts blue to 3 parts yellow glaze. A mixture contains 25 quarts of blue and 9 quarts of yellow glaze?

Answer 1

For every 5 quarts of blue, you should have 3 quarts of yellow. Since you have 25 quarts of blue in the mix (5*5), there should be 3*5 or 15 quarts of yellow. As there are only 9, you need to add 6 quarts of yellow to get the proper ratio of blue to yellow.
