Final answer:
Nisha donates 1/6 of her salary to charity. This problem shows the application of basic fraction operations in a practical situation, such as financial management and charitable giving.
Step-by-step explanation:
Nisha saves 1/3 of her salary and spends 1/2 of it. That means, when we add these fractions together, the total becomes 1/3 + 1/2 = 5/6. Here, we are assuming that the whole salary is represented as 1. Since she spent 5/6 of it, the remaining salary which she donates is 1 - 5/6 = 1/6. Thus, she donates 1/6 of her salary to charity. The value we could learn from Nisha's actions is the importance of financial management and charitable giving.
