What will come in the place of question mark (?) in the following question.

$$-28 + 5 \frac{1}{3} + 8 \frac{4}{5} - 6 \frac{3}{5} + ? = 7 \frac{2}{3}$$​

Value of$$\frac{0.97 \times 0.97 \times 0.97 + 0.03 \times 0.03 \times 0.03}{0.97 \times 1.94 - 1.94 \times 0.03 + 0.03 \times 0.06}$$​ is equal to:

The value of $$\frac{(0.\overline{29} \div 0.\overline{32}) \times 6.6}{0.\overline{95} \div 1.\overline{05} \times 1.\overline{2}}$$​ is

$$4\frac{1}{10}-\left[2\frac{1}{2}-\left\{\frac{5}{6}-\left(\frac{2}{5}+\frac{3}{10}-\frac{4}{15}\right)\right\}\right]$$​on simplification gives

Find the value of $$\left[\left(36 \div 9\right) \times \left\{\frac{56}{8} + \frac{14}{1} \times (6 - 5)\right\}\right]$$​​

The value of $$\frac{2}{5}+\left(\frac{1}{1+\frac{5}{7}}\right)-\frac{2}{5}$$​​

Find the value of  $$\left( \frac{16}{8} \right) \times \left\{ \frac{40}{2} + \frac{11}{6} \times (8 - 2) \right\}$$​​

Simplify: $$\left[\left(\frac{2}{3}\right)+\left(\frac{4}{5}\div \frac{2}{7}\right)\right]\div \left[\left(\frac{3}{2}\right)-\left(\frac{5}{6}\times \frac{3}{4}\right)\right]$$​​

Simplify: $$\left(2\frac{1}{2} + 3.6\right) \div 0.75 + \left(1.25 \times \frac{4}{5}\right)$$​​

Simplify: $$\left( \frac{7}{5} \div \frac{14}{15} \right) \times \left( \frac{10}{7} \div \frac{5}{3} \right)$$​​

Simplify: $$\left( 1.5 + \frac{3}{8} \right)^{3} - \left( \frac{9}{5} \times 1.25 \right)$$​
