Hint
\(5\frac{4}{7}+7\frac{2}{5}\)
\(=5+\frac{4}{7}+7+\frac{2}{5}\)
\(=12+\frac{4}{7}+\frac{2}{5}\)
\(=12+\frac{4\times{5}}{7\times{5}}+\frac{2\times{7}}{5\times{7}}\)
\(=12+\frac{20}{35}+\frac{14}{35}\)
\(=12+\frac{20+14}{35}\)
\(=12+\frac{34}{35}\)
\(=12\frac{34}{35}\)
\(=5+\frac{4}{7}+7+\frac{2}{5}\)
\(=12+\frac{4}{7}+\frac{2}{5}\)
\(=12+\frac{4\times{5}}{7\times{5}}+\frac{2\times{7}}{5\times{7}}\)
\(=12+\frac{20}{35}+\frac{14}{35}\)
\(=12+\frac{20+14}{35}\)
\(=12+\frac{34}{35}\)
\(=12\frac{34}{35}\)
