| To solve this problem, we introduce a conditional variable “X”, through which we denote the number of grams of salt in a solution weighing 720 grams.

Then, based on the data of the problem, we will compose the following proportion: 800 grams of solution are related to 507 grams of salt, as 720 grams of solution are related to X grams of salt.

Then, based on this proportion, we will compose the following equation: X x 800 = 507 x 720.

Solving this equation, we get X equal to 456.3 grams of salt.

Answer: 456.3 grams of salt.
