Answer 1

Resposta:

$u)\frac{10}{5} -\frac{3}{6} \\\\=\frac{10}{5} -\frac{1}{2} \\\\=\frac{20}{10} -\frac{5}{10} \\\\=\frac{20-5}{10} \\\\=\frac{15}{10} \\\\\ =\frac{3}{2}$

$y)\frac{7}{5} +\frac{2}{3} -\frac{1}{3} \\\\=\frac{7}{5} +\frac{1}{3} \\\\=\frac{21}{15} +\frac{5}{15} \\\\=\frac{21+5}{15} \\\\=\frac{26}{15}$
