Answer 1

Нужно привести к общему знаменателю:
$27 \frac{7}{50}+2.36+4 \frac{1}{2}= \frac{1357}{50}+ \frac{236}{100}+ \frac{9}{2}=\frac{1357}{50}+ \frac{118}{50}+ \frac{9}{2}= \frac{1357+118+9*25}{50}= \\ = \frac{1700}{50}=34 \\ 1 \frac{3}{20}+ \frac{617}{100}+ \frac{68}{100}= \frac{23}{20} + \frac{617}{100}+ \frac{68}{100}= \frac{23*5+617+68}{100}= \frac{800}{100}=8$
$\frac{52}{25}+ \frac{6}{10}+ \frac{67}{20}= \frac{52*4+6*10+67*5}{100}= \frac{603}{100}=6.03$
$\frac{51}{8}+ \frac{9125}{1000}+ \frac{54}{100}= \frac{51*125+9125+54*10}{1000}= \frac{16040}{1000}=16.04$
