A beautician's income includes her salary and the tips she gets for her services. During a particular week, if her tips $$\frac{5}{4}$$​ were of her salary, then what fraction of her income came from the tips?

Correct option is D

​Given:

Tips = $$\frac{5}{4}$$​of salary.

Formula Used:

Income = Salary + Tips.

Fraction from tips = $$\frac{\text{Tips}}{\text{Income}}$$​​

Solution:

Let salary = S, Tips = $$\frac{5}{4}S$$​​

Income = $$S + \frac{5}{4}S$$​ = $$\frac{9}{4}S$$​

Fraction from tips = $$\frac{\frac{5}{4}S}{\frac{9}{4}S} = \frac{5}{9}$$​​
