The value of $\left(1-\frac{1}{2}\right)\left(1-\frac{1}{3}\right)\left(1-\frac{1}{4}\right).......\left(1-\frac{1}{10}\right)=$

The vulgar fraction of $0.231$ can be expressed as

If we multiply a fraction by itself, the fraction thus obtained is $\frac{16}{81}$. The original fraction is 

The quotient when $0.00639$ is divided by $0. 213$ is

If the numerator and denominator of a proper fraction are increased by the same quantity, then the resulting fraction is

Simplify:
$\frac{1+\frac{1}{2}}{1-\frac{1}{2}}$ $÷$ $\frac{4}{7}\left(\frac{2}{5}+\frac{3}{10}\right)$of $\left(\frac{\frac{1}{2}+\frac{1}{3}}{\frac{1}{2}-\frac{1}{3}}\right)$

The value of $738.6\times 5.4+7.8÷2.6$ =
