D. $$\frac{1}{2}$$

E. $$\frac{7}{12}$$

Here,

Let's take the total Salary as = 24 (since it is divisible by both 6 and 4)

Now the first part,

$$\frac{1}{6}$$ of salary = $$\frac{1}{6}$$ * 24 = 4

Now, she uses 1/4 more than the car payment for Rent i.e = $$\frac{1}{4} * 4 = 1$$

Total rent paid = $$1 + 4 = 5$$

Combination of both rent and car payment =$$5 + 4 = 9$$

Therefore, fraction of her monthly salary did Mary use that month for the car payment and rent combined = $$\frac{9}{24} = \frac{3}{8}$$
