What will come in place of the question mark (?) in the following questions ?
$$4\frac{1}{2}+(1\div 2\frac{8}{9})-3\frac{1}{13}=?$$
$$\frac{9}{2} + (1\div \frac{26}{9}) - \frac{40}{13}$$ = $$\frac{9}{2} + \frac{9}{26} - \frac{40}{13}$$
= $$\frac{117-80+9}{26}$$ =$$\frac{46}{26}$$
=$$1\frac{10}{13}$$
Option E is the right answer.
