Answer 1

Răspuns:

a=316/9-13/3 amplificam

a=316/9-39/9

a=277/9

b=652/15-1231/30

b=1304/30-1231/30

b=73/30

Answer 2

Răspuns:

    $a=35\frac{1}{9}-4\frac{1}{3} \\a=\frac{316}{9}-\frac{13}{3}  \\a=\frac{316}{9}-\frac{39}{9}  \\a=\frac{277}{9}$

    $b=43\frac{7}{15}-41\frac{1}{30}  \\b=\frac{652}{15}-\frac{1231}{30}  \\b=\frac{1304}{30}-\frac{1231}{30}  \\b=\frac{73}{30}$
