Math CentralQuandaries & Queries


Question from Dan:

A mixture of 1 part sulfur and 2 parts lime is added to soil as an amendment to prevent blossom end rot in tomatoes and green peppers.

 One Tablespoon of the above mixture is added to each hole prior to planting [using the comparative standard of 1 Tablespoon [US] = 0.5 ounce [US liquid], per the conversion factor given on the website,]

 How many ounces of each component must I mix to have an adequate amount to add to 150 planting holes?

 0.5 oz/hole X 150 holes = 75 oz. of mixture required for 150 holes

 75 oz. divided into thirds = 75/3 = 25.

 Therefore, 25 oz. of the total 75 oz. would be sulfur, and 50 oz. would be lime.

 Am I calculating this correctly?

Many thanks for any assistance you can give, and thank you for this excellent website and service

Hi Dan.

You are indeed. Good work!

One thing to be a little cautious of is to be sure you are dealing with volume measurements throughout. If some of the ingredients is measured in weight, then you will have a messier calculation involved the densities of the ingredients.
