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 4

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