[༺ღ¹⁷⁰⁶²⁰¹⁰H𝚘̷àทջ✎﹏ᑭh𝚘̷ทջღ²ᵏ¹⁰༻ღtea...]

\(\frac{25}{7}\times\frac{49}{22}\div\frac{25}{2}\)

\(=\frac{25}{7}\times\frac{49}{22}\times\frac{2}{25}\)

\(=\frac{25\times49\times2}{7\times22\times25}\)

\(=\frac{25\times7\times7\times2}{7\times2\times11\times25}\)

\(=\frac{7}{11}\)

Answer 2

[Nguyễn Minh Hiếu]

\(\frac{25}{7}\times\frac{49}{22}:\frac{25}{2}\)
=\(\frac{25}{7}\times\frac{49}{22}\times\frac{2}{25}\)
=\(\frac{25\times49\times2}{7\times22\times25}\)
=\(\frac{25\times7\times7\times2}{7\times2\times11\times25}\)
=\(\frac{7}{11}\)
