Bronze consists of 3 parts of tin and 17 parts of copper. How much tin is in a bronze part

Bronze consists of 3 parts of tin and 17 parts of copper. How much tin is in a bronze part, if the mass of the part is 660 grams.

Let us calculate from what total number of parts of tin and copper their alloy consists, which is called bronze, when we know, in accordance with the data from the conditions of our assignment, that there are three parts of tin and seventeen parts of copper:

17 + 3 = 20.

Let’s calculate how many grams will fall on one such part, when we know that the mass of a bronze part is six hundred and sixty grams:

660: 20 = 33.

Let’s calculate how many grams of tin were used:

33 * 3 = 99.

Answer: 99 g.
