\(=1\)

1/10 + 20/100 + 300/1000 + 4000/10000

=1/10 + 2/10 + 3/10 + 4/10

=10/10

=1

\(\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{4000}{10000}\)

=\(\frac{1}{10}+\frac{2}{10}+\frac{3}{10}+\frac{4}{10}\)

Nhìn phép tính trên ta thấy: 4 phân số trên đều có thể có MC là 10.
Rút gọn :20/100=2/10;300/1000=3/10;4000/10000=4/10
Ta được phép tính cộng PS : 1/10+2/10+3/10+4/10=10/10=1

\(a,\frac{5}{7}+\frac{7}{13}+\frac{19}{13}+\frac{6}{5}+\frac{9}{7}+\frac{9}{5}.\)

\(=\left(\frac{5}{7}+\frac{9}{7}\right)+\left(\frac{7}{13}+\frac{19}{13}\right)+\left(\frac{6}{5}+\frac{9}{5}\right)\)

\(=\frac{14}{7}+\frac{26}{13}+\frac{15}{5}=2+2+3=7\)

\(b,\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{4000}{10000}\)

chúc bạn học tốt

= 11111

100 + 1000 = 1100

1100+10=1110 

1110+ 10000=11110

`a, 1000 : 100 = 10`

`b, 75 xx 100 = 7500`

`c, 900 xx 10 = 9000`

`d, 8 xx 100 : 10 : 10 xx 10000 = 80000`

\(a,1000:100=10\\ b,75\times100=7500\\ c,900\times10=9000\\ d,8\times100:10:10\times10000\\ =800:10:10\times10000=8\times10000=80000\)

a)\(1000:100=10\)
