Answer 1

4 2/3*6-1 23/42*3 1/13+2 1/8*1 29/51=26  4/7

$1) 4frac{2}{3}*6= frac{14}{3}*6=28 \ \ 2) 1frac{23}{42}*3 frac{1}{13}= frac{65}{42}* frac{40}{13}= frac{13*5}{21*2}* frac{20*2}{13}= frac{100}{21} \ \ 3) 2 frac{1}{8}*1 frac{29}{51}= frac{17}{8}* frac{80}{51}= frac{17}{8}* frac{8*10}{17*3}= frac{10}{3} \ \ 4)28- frac{100}{21}+ frac{10}{3} = frac{28*21-100+10*7}{21}= frac{558}{21}=26 frac{12}{21} =26 frac{4}{7}$
