Вычислите сумму д) 1 11/17+2 15/17 е) 4 13/27+8 17/27

Answer 1

$1 frac{11}{17} + 2 frac{15}{17} = (1 + 2) + ( frac{11}{17} + frac{15}{17} ) = \ 3 + ( frac{26}{17} ) = 3 + (1 + frac{9}{17} ) = 4 frac{9}{17}$

$4 frac{13}{27} + 8 frac{17}{27} = 12 + ( frac{13 + 17}{27} ) = \ 12 + 1 frac{3}{27} = 13 frac{1}{9}$
