 | 6 3/7|: |-9| +4 1/3;
вычислите помогите!!!!!!

Answer 1

1.
$7- frac{3.6}{1.2}=4$
2.
$frac{7}{24} * frac{8}{7} *3= frac{7*8*3}{8*3*7} =1$
3.
$frac{27}{10} * frac{5}{9} * frac{14}{9} = frac{27*5*14}{10*9*9} = frac{3*14}{2*9} = frac{42}{18} =2 frac{1}{3}$
4.
$frac{45}{7*9} + frac{13}{3} = frac{5}{7} + frac{13}{3} = frac{15+91}{21}= 5 frac{1}{21}$
