Answer 1

a)

$40 + 3 + \frac{5}{10} + \frac{6}{100}$

${\frac{40}{1}}^{100} + {\frac{3}{1}}^{100} + { \frac{5}{10} }^{10} + \frac{6}{100}$

$\frac{4000}{100} + \frac{300}{100} + \frac{50}{100} + \frac{6}{100}$

$= \frac{4356}{100} = 43.56$

b)

$3 \times 1000 + 0.10 + 5 + \frac{1}{10} + \frac{0}{100} + \frac{7}{1000}$

${ \frac{300}{1} }^{1000} + { \frac{0.10}{1} }^{1000} + { \frac{5}{1} }^{1000} + { \frac{1}{10} }^{100} + { \frac{0}{100} }^{10} + \frac{7}{1000}$

$\frac{300000}{1000} + \frac{150}{1000} + \frac{5000}{1000} + \frac{100}{1000} + \frac{0}{1000} + \frac{7000}{1000}$

$\frac{312250}{1000} = 312.25$
