A farmer mixes three equal quantities of fertilisers. The first one contains 1/10 nitrogen, the second contains 9/50 nitrogen and the third contains 3/60 nitrogen. What is the fraction of nitrogen in the mixture?

Because quantities are equal, we average the fractions. Adding 1/10, 9/50 and 1/20 gives 33/100; dividing this sum by 3 yields a final nitrogen fraction of 11/100 or 0.11.

    1. When three equal quantities of fertilisers are mixed, each contributes equally to the total volume. We calculate the arithmetic mean of the three nitrogen fractions. Simplifying 3/60 to 1/20 and using the common denominator 100, the sum is 10/100 + 18/100 + 5/100 = 33/100. Dividing this sum by 3 gives the final combined fraction of nitrogen in the mixture as 11/100.
