1 /2/3 = 5/3
1/2/3 = 5/3
vậy hai hỗn số bằng nhau
nho k minh nha
\(\frac{1}{\frac{2}{3}}\)=\(\frac{1}{\frac{2}{3}}\)
tk mình nhé
\(\frac{1}{\frac{2}{3}}\)>\(\frac{\frac{1}{2}}{3}\)

So sánh:\(\frac{\frac{\frac{1}{2}}{\frac{3}{4}}}{\frac{\frac{5}{6}}{\frac{7}{8}}}+\frac{\frac{\frac{8}{7}}{\frac{6}{5}}}{\frac{\frac{4}{3}}{\frac{2}{1}}}\) và\(\frac{\frac{\frac{1}{2}}{\frac{3}{4}}+\frac{\frac{8}{7}}{\frac{6}{5}}}{\frac{\frac{5}{6}}{\frac{7}{8}}+\frac{\frac{4}{3}}{\frac{2}{1}}}\)và \(\frac{\frac{\frac{1}{2}+\frac{8}{7}}{\frac{3}{4}+\frac{6}{5}}}{\frac{\frac{5}{6}+\frac{4}{3}}{\frac{7}{8}+\frac{2}{1}}}\)và\(\frac{\frac{\frac{1+8}{2+7}}{\frac{3+6}{4+5}}}{\frac{5+4}{\frac{6+3}{2+1}}}\)
so sánh:\(\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+....+\frac{1}{100^2}\) với \(\frac{2}{3}\)
so sánh B = \(\frac{1}{1+2}+\frac{1}{1+2+3}+\frac{1}{1+2+3+4}+.....+\frac{1}{1+2+3+4+...+2019}\)
với 1
So sánh :
\(\frac{1}{3}+\frac{1}{31}+\frac{1}{35}+\frac{1}{37}+\frac{1}{47}+\frac{1}{53}+\frac{1}{61}\) và \(\frac{1}{2}\)
so sánh:
a)\(\frac{201,7x2018+1}{201,8x2019+1}và\frac{201,6x2017+1}{201,7x2018+1}\) b)\(\frac{1}{5}+\frac{1}{6}+\frac{1}{7}+\frac{1}{8}+\frac{1}{9}+\frac{1}{10}+\frac{1}{11}+...+\frac{1}{14}và\frac{3}{2}\)

\(B=\frac{2}{5}.\frac{4}{7}.\frac{6}{9}...\frac{998}{1001}\)
So sánh A và B
So sánh \(A\)với\(13\),biết rằng:
\(A=\frac{13}{15}+\frac{7}{5}+\frac{3}{4}+\frac{1}{5}+\frac{1}{7}+\frac{19}{20}+\frac{5}{4}+\frac{1}{3}+\frac{1}{6}+\frac{1}{13}+\frac{17}{23}+\frac{9}{8}+\frac{2}{5}+\frac{1}{7}+\frac{1}{25}+\frac{3}{2}+\frac{1}{8}+\frac{1}{19}+\frac{1}{9}+\frac{1}{97}\)
Hãy so sánh A và B biết :
A = \(\frac{1}{1}-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+...+\frac{1}{99}\)\(-\frac{1}{100}\)
B = \(\frac{1}{51}+\frac{1}{52}+\frac{1}{53}...+\frac{1}{100}\)
