Question

1)11/18-4/9*3/16 2)1 3/5*3/4+1 3/8

Answer 1

$frac{11}{18}- frac{4}{9}* frac{3}{16}= frac{11}{18}- frac{1*1}{3*4}= frac{11}{18}- frac{1}{12}= frac{22-3}{36} = frac{19}{36}$

$1 frac{3}{5} * frac{3}{4} +1 frac{3}{8}= frac{8}{5}* frac{3}{4}+1 frac{3}{8}= frac{6}{5}+ frac{11}{8}= frac{48+55}{40} = frac{103}{40}=2 frac{23}{40}$
