199619961996/149714971497=199619961996x 101010101010/149714971497x101010101010=1996/1497

Vậy kết quả là 1996/1497

1818181818/8181818181=2/9.

\(\frac{199619961996}{149714971497}=\frac{1996.100010001}{1497.100010001}=\frac{1996}{1497}=\frac{2000-4}{1500-3}=\frac{4\left(500-1\right)}{3\left(500-1\right)}=\frac{4}{3}\)

\(\frac{199619961996}{149714971497}=\frac{1996.100010001}{1497.100010001}=\frac{1996}{1497}=\frac{2000-4}{1500-3}=\frac{4\left(500-1\right)}{3\left(500-1\right)}=\frac{4}{3}\)

272727/292929=272727 : 10101/292929 : 10101

                         =27/29

CHÚC BẠN HỌC GIỎI

a)27/29

272727/292929=272727÷10101/292929÷10101=27/29

1818181818/8181818181=1818181818÷909090909/8181818181÷909090909=2/9

ta lấy : 2727-1818=909

2727:909=3

1818:909=2

vậy bằng 3/2

a) 2727=27x101

   1818=18x101

nên 2727 / 1818 = 27 x 101 / 18 x 101 = 27 / 18 = 3/2 ( chia cả tử và mẫu cho 9)

b) tương tự có : 123 x 1001 / 345 x 1001 = 123 / 345 = 41 / 115 ( chia cả tử và mẫu cho 3)

2727/1818 = 303/202

\(\frac{98}{100}=\frac{49}{50}\)

\(\frac{123123}{234234}=\frac{41}{78}\)

\(\frac{20182018}{20152019}\approx1.001488635\)
