Question

\(\sqrt{\frac{4}{9}}:\sqrt{\frac{25}{81}}-\left|-1\frac{7}{8}\right|\)

Answer 1

=2/3:5/9-15/8

=2/3*9/5-15/8

=6/5-15/8

=-27/40

Answer 2

\(\sqrt{\frac{4}{9}}:\sqrt{\frac{25}{81}}-|-1\frac{7}{8}|\)

\(=\frac{2}{3}:\frac{5}{9}-1\frac{7}{8}\)

\(=\frac{2}{3}\times\frac{9}{5}-\frac{15}{8}\)

\(=\frac{6}{5}-\frac{15}{8}\)

\(=\frac{27}{40}\)

Answer 3

 \(\sqrt{\frac{4}{9}}:\sqrt{\frac{25}{81}}-\left|-1\frac{7}{8}\right|\)

\(=\frac{2}{3}:\frac{5}{9}-\left|\frac{-15}{8}\right|\)

\(=\frac{2}{3}\cdot\frac{9}{5}-\frac{15}{8}\)

\(=\frac{6}{5}-\frac{15}{8}\)

\(=\frac{3}{40}\)

Answer 4

\(\sqrt{\frac{4}{9}}:\sqrt{\frac{25}{81}}-\left|-1\frac{7}{8}\right|\)

\(=\frac{2}{3}:\frac{5}{9}-\frac{15}{8}\)

\(=\frac{2}{3}\cdot\frac{9}{5}-\frac{15}{8}\)

\(=\frac{6}{5}-\frac{15}{8}\)

\(=\frac{-27}{40}\)
