Answer 1

$\tt \:( a.) 20 + 9 + \frac{4}{10} + \frac{1}{100} \\ \tt \: = \frac{200 + 90 + 4}{10} + \frac{1}{100} \\ \tt \: = \frac{294}{10} + \frac{1}{100} \\ \tt \: = \frac{2940 + 1}{100} \\ \tt \: = { \boxed{ \bf294.01}} \\ \tt(b.)137 + \frac{5}{100} \\ \tt \: = \frac{13700 + 5}{100} \\ \tt \: = \frac{13705}{100} = { \boxed{ \bf{137.05}}} \\ \tt(c.) \frac{7}{10} + \frac{6}{100} + \frac{4}{1000} \\ \tt \: = \frac{700 +60 + 4 }{1000} \\ \tt \: = \frac{764}{1000} \\ \tt { \boxed{ \bf{ = {0.764}}}} \\ \tt \: (d.)23 + \frac{2}{10} + \frac{6}{1000} \\ \tt \: = 23 + 0.2 + 0.006 \\ \tt \: = { \boxed{ \bf{23.206}}} \\ \tt \: (e.)700 + 20 + 5 + \frac{9}{100} \\ \tt = 700 + 20 + 5 + 0.09 \\ \tt = { \boxed{ \bf{725.09}}}$
