The alloy contains 27.3 g of silver, which is 0.35 of the alloy, the rest is other metals. find the mass of other metals in the alloy.

The share of silver in the total alloy is 0.35 * 100% = 35%.

Other metals account for 100% – 35% = 65%.

Let the mass of other alloys = X;

Let’s build a proportion: the mass of silver will relate to the percentage of silver in the same way as X will relate to the percentage of other metals:

27.3 / 35 = X / 65;

X = 27.3 * 65/35 = 50.7 g.
