Question

4+2/3 , 3/11 + 7/11 , 4/7+3/7,1-5/8,5 8/9-3 1/9 4 7/12 + 2 5/12 3 9/16 + 1 11/16 , 8 1/5 - 6 4/5

Answer 1

$4 + frac{2}{3} =4 frac{2}{3} \ \ frac{3}{11} + frac{7}{11} = frac{3+7}{11} = frac{10}{11} \ \ frac{4}{7} + frac{3}{7} = frac{7}{7} =1 \ \ 1- frac{5}{8} = frac{8-5}{8} = frac{3}{8} \ \ 5 frac{8}{9} -3 frac{1}{9} =(5-3) + frac{8-1}{9} = 2 frac{7}{9} \ \ 4 frac{7}{12} +2 frac{5}{12} = 6+ frac{12}{12} =7 \ \ 3 frac{9}{16} + 1 frac{11}{16} = 4+1 frac{4}{16} =5 frac{4}{16} =5 frac{1}{4}$
$8 frac{1}{5} -6 frac{4}{5} = (7+ frac{5+1}{5} ) - 6 frac{4}{5} = 1 frac{2}{5}$
