Question

[BTS ơi BTS vô địch]

tính nhanh

50/51 x 51/15 : 34/15

Answer 1

[Huỳnh Quang Sang]

\(\frac{50}{51}\cdot\frac{51}{15}:\frac{34}{15}\)

\(=\frac{50}{51}\cdot\frac{51}{15}\cdot\frac{15}{34}=\frac{50\cdot51\cdot15}{51\cdot15\cdot34}=\frac{50}{34}=\frac{25}{17}\)

Answer 2

[%$H*&]

\(\frac{50}{51}.\frac{51}{15}:\frac{34}{15}\)

\(=\frac{50.51.15}{51.15.34}\)

\(=\frac{50}{34}=\frac{25}{17}\)
