Question

-3 5/6 + 10 3/8 подробно

Answer 1

$-3frac{5}{6}+10frac{3}{8}=-frac{23}{6}+frac{83}{8}=frac{83*3}{24}-frac{23*4}{24}=frac{249}{24}-frac{92}{24}= frac{157}{24}=6frac{13}{24}$

Answer 2

$displaystyle -3frac{5}{6}+10frac{3}{8}=10+frac{3*3}{8*3}-(3+frac{5*4}{6*4})=\ \ \ 7+(frac{9}{24}-frac{20}{24})=7-frac{11}{24}=6frac{13}{24};$

Или так:

$displaystyle -3frac{5}{6}+10frac{3}{8}=frac{83}{8}-frac{23}{6}=frac{83*3-23*4}{24}=frac{249-92}{24}=frac{157}{24}=6frac{13}{24};$
