If 2/5 of  a government employee's income is spent on utilities, what fraction of the income is not spent on utilities? 

If $ \frac{2}{5} $ of a government employee's income is spent on utilities, the fraction of the income that is not spent on utilities can be calculated as follows:

1. The total income is represented by $ 1 $ (or $ \frac{5}{5} $).
2. The fraction spent on utilities is $ \frac{2}{5} $.
3. The fraction not spent on utilities is:

\[
1 - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{3}{5}
\]

So, $ \frac{3}{5} $ of the income is not spent on utilities.

2. What is the total amount spent on utilities if the employee's income is $5000 per month?
3. If the employee's income increases by 10%, what will be the new fraction spent on utilities?
4. If $ \frac{1}{3} $ of the remaining income is saved, what fraction of the original income is saved?
5. How would the fraction change if the amount spent on utilities increased to $ \frac{3}{5} $ of the income?
