Question

$\frac{5 \frac{1}{7} \times 5 \frac{1}{4} + 5 \frac{5}{8} \times 3 \frac{1}{5} }{10 \frac{5}{13} \div 1 \frac{1}{26} }$

Answer 1

$\frac{5 \frac{1}{7} \cdot 5 \frac{1}{4} + 5 \frac{5}{8} \cdot 3 \frac{1}{5} }{10 \frac{5}{13}:1 \frac{1}{26} } =$

$\frac{ \frac{36}{7} \cdot \frac{21}{4} + \frac{45}{8} \cdot \frac{16}{5} }{\frac{135}{13}: \frac{27}{26} } =$

$\frac{ 27+ 18}{\frac{135}{13} \cdot \frac{26}{27} } =$

$\frac{ 45}{10} =4,5$

Answer 2

$\frac{5\frac{1}{7}\cdot 5\frac{1}{4}+5\frac{5}{8}\cdot 3\frac{1}{5}}{10\frac{5}{13}:1\frac{1}{26}}=\frac{\frac{36}{7}\cdot \frac{21}{4}+\frac{45}{8}\cdot \frac{16}{5}}{\frac{135}{13}:\frac{27}{26}}=\frac{9\cdot 3+9\cdot 2}{\frac{135}{13}\cdot \frac{26}{27}}=\frac{9\cdot (3+2)}{5\cdot 2}=\frac{9}{2}=4,5$
