The alloy contains 14% zinc. How many kilograms of alloy do you need to take to contain 5.6 kg of zinc?

We denote the required weight of the alloy as x kg.

This mass will refer to 100% in the same way as 5.6 kg of zinc refers to 14% alloy.

Thus, we get the following proportion:

x / 100% = 5.6 / 14%.

14 * x = 5.6 * 100.

14 * x = 560.

x = 560/14 = 40 kg.

Answer:

The alloy mass should be equal to 80 kg.
