35 / 17 - 84 / 32 - 18 / 17 + 26 / 16
= ( 35 / 17 - 18 / 17 ) - ( 21 / 8 - 13 / 8)

\(=1-1\)
\(=0\)
35 / 17 - 84 / 32 - 18 / 17 + 26 / 16

tính hợp lý : \(\frac{\frac{3}{3}-\frac{3}{5}+\frac{3}{11}+\frac{3}{13}}{\frac{7}{3}-\frac{7}{5}+\frac{5}{11}+\frac{5}{13}}\)
Tính nhanh!!\(\frac{17}{35}.37\frac{19}{25}+1\frac{8}{7}.33\frac{7}{25}+\left(\frac{17}{35}-1\frac{8}{17}\right).32\frac{6}{25}\)Các anh, chị giúp em ạ
Tính bằng cách hợp lí nhất
a) A = \(\frac{\left(1+17\right)\left(1+\frac{17}{2}\right)\left(1+\frac{17}{3}\right)...\left(1+\frac{17}{19}\right)}{\left(1+19\right)\left(1+\frac{19}{2}\right)\left(1+\frac{19}{3}\right)..\left(1+\frac{19}{17}\right)}\)
b) B = \(\left(\frac{1}{2}-1\right)\left(\frac{1}{3}-1\right)...\left(\frac{1}{99}-1\right)\left(\frac{1}{100}-1\right)\)
*so sánh:
a)\(\frac{-12}{17}\)và \(\frac{13}{-18}\)
b) \(\frac{-17}{26}\)và\(\frac{-16}{27}\)
* Tính hợp lí
\(\frac{2}{39}+\frac{1}{15}+\frac{2}{153}\)/ \(\frac{1}{34}+\frac{3}{20}+\frac{3}{26}\): \(1+\frac{2}{71}\frac{5}{121}\)/ \(\frac{65}{121}-\frac{26}{71}-13\)
