Học good

Answer 2

\(\frac{17}{4}\)

Answer 3

\(\frac{7}{4}+3-\frac{1}{2}\)

\(=\frac{7}{4}+\frac{3}{1}-\frac{1}{2}\)

\(=\frac{7}{4}+\frac{12}{4}-\frac{1}{2}\)

\(=\frac{9}{4}-\frac{1}{2}\)

\(=\frac{9}{4}-\frac{2}{4}\)

\(=\frac{7}{4}\)

Answer 4

\(\frac{7}{4}+3-\frac{1}{2}\)

\(=\frac{7}{4}+\frac{12}{4}-\frac{2}{4}\)=\(=\frac{17}{4}\)
