So sánh các phân số khi thực hiện phép tính rút gọn :
a) A =\(\frac{3535x232323}{353535x2323}\) B =\(\frac{3535}{3534}\) C = \(\frac{2323}{2322}\)
b) A = \(\frac{777x677677}{777777x677}\) B = \(\frac{677677}{677676}\) C = \(\frac{777777}{777776}\)
a) Ta có: \(A=\frac{3535.232323}{353535.2323}=\frac{35.101.23.10101}{35.10101.23.101}=\frac{35}{23}\)
\(B=\frac{3535}{3434}=\frac{35.101}{34.101}=\frac{35}{34}\)
\(C=\frac{2323}{2322}=\frac{2323}{2322}\)
