Question

Вычислите:а)1 5/16+2 3/8. Б)17/18-5/6

Answer 1

1 5/16+2 3/8=21/16+38/16=59/16=3 11/16=3,6875
17/18-5/6=17/18-15/18=2/18=1/9

Answer 2

$1frac{5}{16} +2 frac{3}{8} =3 frac{11}{16} \ \ 1 frac{5*1}{16} +2 frac{3*2}{16} =1+2 frac{5+6}{16} =3 frac{11}{16} \ \ frac{17}{18} - frac{5}{6} = frac{1}{9} \ \ frac{17*1}{18} - frac{5*3}{18} = frac{17-15}{18} = frac{2}{18} = frac{1}{9} \ \ frac{2}{18} = frac{2}{2*3*3} = frac{1}{9}$
