Question

$3 frac{2}{7} -(2* frac{3}{14} +1 frac{1}{7} )*2=$

Answer 1

$3 frac{2}{7} -(2* frac{3}{14} +1 frac{1}{7} )*2= \ \ 1)2* frac{3}{14}= frac{3}{7} \ \ 2)frac{3}{7}+1 frac{1}{7}=frac{3}{7}+frac{8}{7}= frac{3+8}{7} = frac{11}{7} \ \ 3) frac{11}{7}*2= frac{22}{7} \ \ 4) 3 frac{2}{7} -frac{22}{7}= frac{23}{7} -frac{22}{7}= frac{23-22}{7} = frac{1}{7}$

Answer 2

$3 frac{2}{7} -(2* frac{3}{14} +1 frac{1}{7} )*2= frac{1}{7} \ 1)2* frac{3}{14}= frac{2*3}{14} = frac{3}{7} \ 2) frac{3}{7} +1 frac{1}{7} =1 frac{4}{7} \ 3)1 frac{4}{7} *2= frac{11*2}{7} = frac{22}{7} =3 frac{1}{7} \ 4)3 frac{2}{7} -3 frac{1}{7} = frac{1}{7}$
