Question

1) (4 1/3+3 1/5):113
2) (6-7 1/8)×(2/9+2/3)

Answer 1

1) (4 1/3+3 1/5):113

$frac{13}{3}+frac{16}{5}   =frac{65}{15} +frac{48}{15} =frac{113}{15}$

$frac{113}{15}:113=frac{113}{15}*frac{1}{113}  =frac{1}{15}$

2)(6-7 1/8)×(2/9+2/3)

$6-7frac{1}{8}=6-frac{57}{8}=frac{48}{8} -frac{57}{8} =-frac{9}{8}$

$frac{2}{9} +frac{2}{3}=frac{2}{9}+frac{6}{9} =frac{8}{9}$

$-frac{9}{8}*frac{8}{9}  =-1$
