thực hiện phép tính

1 : \(\frac{99}{100}\): \(\frac{98}{99}\):\(\frac{97}{98}\): ... : \(\frac{2}{3}\): \(\frac{1}{2}\)

Answer 1

 1x100/99x99/98x98/97x.....x3/2x2

 1x100

 100

Answer 2

\(1:\frac{99}{100}:\frac{98}{99}:\frac{97}{98}:.........:\frac{2}{3}:\frac{1}{2}\)

\(=1.\frac{100}{99}.\frac{99}{98}.\frac{98}{97}......\frac{3}{2}.\frac{2}{1}\)

\(=\frac{1.100.99.98....3.2}{99.98.97......2.1}\)

\(=100\)
