The mass of the copper alloy The animation of gold and silver in the alloy is 5: 3.

The mass of the copper alloy The animation of gold and silver in the alloy is 5: 3. How many grams of silver is contained in an alloy weighing 56 g.

Let’s denote one part by x.

Let’s determine the mass of gold in the alloy:

5 * x = 5x g.

Let’s find the mass of silver in the alloy:

3 * x = 3x g.

Since the mass of the alloy is 56 g, then we compose and solve the equation:

5x + 3x = 56,

8x = 56,

x = 56: 8,

x = 7.

One part is equal to x = 7 g.

Find out how many grams of silver are contained in an alloy weighing 56 g:

3 * 7 = 21 (g).

Answer: 21 grams of silver is contained in an alloy weighing 56 g.
