Answer 2

= 17/3 - 7/4 * 12/5 = 17/3 - 84/20 = 340/60 - 252/60 = 88/60 = 1 và 28/60

Answer 3

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

Answer 4

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

Answer 5

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)

Answer 6

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)

Answer 7

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)

Answer 8

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)

Answer 9

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)

Answer 10

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)

Answer 11

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)

Answer 12

      \(5\frac{2}{3}-1\frac{3}{4}\text{ x }2\frac{2}{5}\)

\(=\frac{17}{3}-\frac{7}{4}\text{ x }\frac{12}{5}\)

\(=\frac{17}{3}-\frac{21}{5}\)

\(=\frac{85}{15}-\frac{63}{15}\)

\(=\frac{22}{15}\)

\(=1\frac{7}{15}\)
