Question

so sánh phân số:

\(\frac{111111}{151515}và\frac{11022}{15030}\)

Answer 1

Ta có: \(\frac{111111}{151515}=\frac{11\times10101}{15\times10101}=\frac{11}{15}\); \(\frac{11022}{15030}=\frac{11\times1002}{15\times1002}=\frac{11}{15}\)

Vậy \(\frac{111111}{151515}=\frac{11022}{15030}=\frac{11}{15}\)

Answer 2

\(\frac{111111}{151515}và\frac{11022}{15030}\)

\(\frac{111111}{151515}=\frac{11x10101}{15x10101}=\frac{11}{15}\)

\(\frac{11022}{15030}=\frac{11022:1002}{15030:1002}=\frac{11}{15}\)

Vậy hai phân số bằngnhau

Answer 3

So sánh phân số :

        \(\frac{111111}{151515}và\frac{11022}{15030}\)

Ta có : \(\frac{111111}{151515}=\frac{11\times10101}{15\times10101}=\frac{11}{15}\); \(\frac{11022}{15030}=\frac{11\times1002}{15\times1002}=\frac{11}{15}\)

Mà \(\frac{11}{15}=\frac{11}{15}\)

\(\Rightarrow\frac{11111}{151515}=\frac{11022}{15030}\)
