3257/1000 

Ta có : 7/10 = 700/1000 ; 91/100=910/1000 ; 37/100=370/1000

      700/1000 + 910/1000+ 370/1000 + 549/1000 + 728/1000 

       =700 + 910 + 370 + 549 + 728 / 1000

       =3257/1000

\(\frac{7}{10}+\frac{91}{100}+\frac{37}{1000}+\frac{547}{1000}+\frac{728}{1000}=\frac{651}{200}\)

\(\frac{7}{10}+\frac{91}{100}+\frac{37}{100}+\frac{547}{1000}+\frac{728}{1000}\)

\(=\frac{651}{200}\)

Chúc bạn học tốt ~
