Three friends $A, B$ and $C$ have some money. If $A$ has $\frac{3}{10}$ of the total money, $B$ has $\frac{7}{15}$ of the total money and $C$ has $\frac{7}{30}$ of the total money. Who has the biggest share of the money? If the total money is $Rs. 1500$, then how much money does $A$ have?

Priyanka spends $\frac{2}{15}$ of her income on clothes, $\frac{1}{9}$ of her income on entertainment, $\frac{4}{15}$ of her income on rent and $\frac{1}{3}$ of income on food and she saves the remaining amount of $Rs. 10,500$. What is the income of Priyanka?

What is the number exactly halfway between $\frac{1}{10}$ and $\frac{1}{8}$?

Simplify:

$\left[5+\frac{1}{12} \text{of} \left\{38-\left(10+\overline{7-3}\right)+\frac{1}{2} \text{of} 24\right\}-3\right]$

Express $0.\overline{6}$ in the form of a fraction.
