Question

1/8 + 1/12 + 3/8 + 5/12, 5/11 + 2/3 + 1/9 + 6/11 найдите значение выражений

Answer 1

1.
$frac{1}{8} + frac{1}{12} + frac{3}{8} + frac{5}{12} =( frac{1}{8} + frac{3}{8})+( frac{1}{12} + frac{5}{12} )= frac{4}{8} + frac{16}{12} = frac{1}{2} + frac{1}{2} =1$

2.
$frac{5}{11} + frac{2}{3} + frac{1}{9} + frac{6}{11} =( frac{5}{11} + frac{6}{11} )+( frac{4}{9} + frac{1}{9} )= frac{11}{11} + frac{5}{9} =1 frac{5}{9}$
