Question

\(\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+2\frac{1}{8}\)

Answer 1

= \(\frac{5}{8}.\left(\frac{5}{12}+\frac{7}{12}\right)+2\frac{1}{8}\)

=> \(\frac{5}{8}.1+2\frac{1}{8}\)=> \(\frac{5}{8}+\frac{17}{8}=\frac{22}{8}=\frac{11}{4}\)

Answer 2

\(\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+2\frac{1}{8}=\frac{-5}{8}.\left(\frac{5}{12}+\frac{7}{12}\right)+\frac{17}{8}=\frac{-5}{8}.1+\frac{17}{8}=\frac{-5}{8}+\frac{17}{8}=\frac{12}{8}=\frac{3}{4}\)

Answer 3

\(\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+2\frac{1}{8}\)

\(=\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+\frac{17}{8}\)

\(=\frac{-5}{8}.\left(\frac{5}{12}+\frac{7}{12}\right)+\frac{17}{8}\)

\(=\frac{-5}{8}.1+\frac{17}{8}\)

\(=\frac{-5}{8}+\frac{17}{8}\)

\(=\frac{12}{8}=\frac{3}{2}\)

Answer 4

\(\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+2\frac{1}{8} \)

\(=\frac{-5}{8}(\frac{5}{12}+\frac{7}{12})+2\frac{1}{8} \)

\(=\frac{-5}{8}.1+2\frac{1}{8} \)

\(=\frac{-5}{8}+2\frac{1}{8} \)

\(=\frac{-5}{8}+\frac{17}{8} \)

\(=\frac{-5+17}{8} \)

\(=\frac{12}{8} \)

\(=\frac{3}{2} \)

Answer 5

\(\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+2\frac{1}{8}\)

\(=\frac{-5}{8}.\frac{5}{12}+\frac{-5}{8}.\frac{7}{12}+\frac{17}{8}\)

\(=\frac{-5}{8}\left(\frac{5}{12}+\frac{7}{12}\right)+\frac{17}{8}\)

\(=\frac{-5}{8}.1+\frac{17}{8}\)

\(=\frac{-5}{8}+\frac{17}{8}\)

\(=\frac{3}{2}\)
