вычислете пожалуйста надо срочно!!!!!!!

Answer 1

$frac{1}{9} + frac{1}{27} = frac{3}{27} + frac{1}{27} = frac{4}{27}; frac{13}{11} : frac{2}{26} = frac{13}{11} * frac{26}{2}= frac{338}{22}=15 frac{8}{22}=15 frac{4}{11}$$frac{1}{9} + frac{1}{27} = frac{3}{27} + frac{1}{27} = frac{4}{27}; frac{13}{11} : frac{2}{26} = frac{13}{11} * frac{26}{2}= frac{338}{22}=15 frac{8}{22}=15 frac{4}{11}$$frac{1}{9} + frac{1}{27} = frac{3}{27} + frac{1}{27} = frac{4}{27}; frac{13}{11} : frac{2}{26} = frac{13}{11} * frac{26}{2}= frac{338}{22}=15 frac{8}{22}=15 frac{4}{11}$
