Water is 10.5 times lighter than silver, and platinum is 21.45 times heavier than silver. How many times is platinum heavier than water?

Let us denote by m the mass of water.

Let us express through m first the mass of silver, and then the mass of platinum.

In the initial data for this task, it is reported that water is 10.5 times lighter than silver.

Therefore, silver is 10.5 times heavier than water and the mass of silver is 10.5 * m.

Also in the condition of the problem it is said that platinum is 21.45 times heavier than silver, therefore, the mass of platinum is 21.45 * 10.5 * m = 225.225 * m.

Dividing the mass of platinum by the mass of water, we find how many times the platinum is heavier than water:

225.225 * m / m = 225.225.

Answer: 225.225 times.
