Answer 2

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

= \(\frac{12}{12}+\frac{6}{12}+\frac{4}{12}+\frac{3}{12}\)

= \(\frac{25}{12}\)

Answer 3

Trả lời : \(1+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}\)

\(=\frac{12}{12}+\frac{6}{12}+\frac{4}{12}+\frac{3}{12}\)

\(=\frac{25}{12}\)

\(\downarrow\)

Answer 4

\(1+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}=\frac{24}{24}+\frac{12}{24}+\frac{8}{24}+\frac{6}{24}=\frac{50}{24}\)
 

Answer 5

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

=  \(\frac{12}{12}+\frac{6}{12}+\frac{4}{12}+\frac{3}{12}\)

= \(\frac{25}{12}\)
