Question

Tìm số tự nhiên X biết: \(1\frac{1}{5}\) x \(1\frac{1}{6}\) x \(1\frac{1}{7}\) x ... x \(1\frac{1}{2014}\)
Trả lời: X = 

 

Answer 1

X=\(\frac{6}{5}.\frac{7}{6}....\frac{2015}{2014}\)

   =\(\frac{2015}{5}\)

  =403

Answer 2

 6/5x7/6x...x2015/2014

=1/10020

Answer 3

X=403 nhé

Answer 4

Nhầm.

6/5x7/6x...x2015/2014

Rút gọn rồi ta được:

=2015/5

=403

Answer 5

      \(1\frac{1}{5}.1\frac{1}{6}.1\frac{1}{7}.........\frac{1}{2014}\)

\(=\frac{6}{5}.\frac{7}{6}.\frac{8}{7}........\frac{2015}{2014}\)

\(=\frac{6.7.8..........2015}{5.6.7..........2014}\)

\(=\frac{2015}{5}=403\)
