Question

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

Answer 1

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

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