Question

4 7/9•1 13/14-3 7/12•1 13/14+1 13/14•1 13/18

Answer 1

$4 frac{7}{9} * 1 frac{13}{14} - 3 frac{7}{12} * 1 frac{13}{14} + 1 frac{13}{14} * 1 frac{13}{18} = 1 frac{13}{14} *( 4frac{7}{9} - 3frac{7}{12} +1 frac{13}{18} )=$
$frac{27}{14} *( frac{43}{9} - frac{43}{12} + frac{31}{18} )= frac{27}{14} * frac{172-129+62}{36} = frac{27}{14} * frac{105}{36} = frac{27}{14} * frac{35}{12} =$
$frac{9}{2} * frac{5}{4} = frac{45}{8} = 5 frac{5}{8} = 5,625$
