Question

1 13/15 . 0,75 - (11/20 + 25/100) : 7/5

Answer 1

\(1\frac{13}{15}.0,75-\left(\frac{11}{20}+\frac{25}{100}\right):\frac{7}{5}\)

\(=\frac{28}{15}.\frac{3}{4}-\frac{4}{5}:\frac{7}{5}\)

\(=\frac{7}{5}-\frac{4}{7}\)

\(=\frac{29}{35}\)

Answer 2

\(1\frac{13}{15}\cdot0,75-\left(\frac{11}{20}+\frac{25}{100}\right):\frac{7}{5}\)

\(=\frac{28}{15}\cdot\frac{3}{4}-\frac{4}{5}:\frac{7}{5}\)

\(=\frac{7}{5}-\frac{4}{7}\)

\(=\frac{29}{35}\)

Answer 3

\(\frac{29}{35}\)

Answer 4

\(1\frac{13}{15}.0,75-\left(\frac{11}{20}+\frac{25}{100}\right):\frac{7}{5}\)

\(=\frac{28}{15}.\frac{3}{4}-\frac{4}{5}.\frac{5}{7}\)

\(=\frac{7}{5}-\frac{4}{7}\)

\(=\frac{29}{35}\)
