Answer 1

Resolvemos :

$1) \frac{6}{13} \times \frac{1}{5} = \frac{6 \times 1}{13 \times 5} = \boxed{ \red{\frac{6}{65} }}$

$2) \frac{1}{8} + \frac{7}{15} = \frac{1 \times 15}{8 \times 15} = \frac{7 \times 8}{15 \times 8} = \frac{15}{20} + \frac{56}{120} = \frac{15 + 56}{120} = \boxed{ \red{\frac{71}{120} }}$

$3) \frac{5}{8} - \frac{1}{4} = \frac{5}{8} - \frac{1 \times 2}{4 \times 2} = \frac{5}{8} - \frac{2}{8} = \frac{5 - 2}{8} = \boxed{ \red {\frac{3}{8} }}$

$4) \frac{2}{3} - \frac{1}{5} = \frac{2 \times 5}{3 \times 5} - \frac{1 \times 3}{5 \times 3} = \frac{10}{15} - \frac{3}{15} = \frac{10 - 3}{15} = \boxed{ \red{\frac{7}{15} }}$

$5)\frac{3}{5} - \frac{4}{7} = \frac{3 \times 7}{5 \times 7} - \frac{4 \times 5}{7 \times 5} = \frac{21}{35} - \frac{20}{35} = \frac{21 - 20}{35} = \boxed{ \red{\frac{1}{35} }}$

$6) \frac{7}{8} - \frac{1}{3} = \frac{7 \times 3}{8 \times 3} - \frac{1 \times 8}{3 \times 8} = \frac{ 21}{24} - \frac{8}{24} = \frac{21 - 8}{24} = \boxed{ \red{\frac{13}{24} } }$

$7) \frac{3}{11} \times \frac{7}{8} = \frac{3 \times 7}{11 \times 8} = \frac{21}{11 \times 8} = \boxed{ \red{\frac{21}{88} }}$

$8) \frac{7}{10} \times \frac{5}{6} = \frac{7}{2} \times \frac{1}{6} = \frac{7 \times 1}{2 \times 6} = \frac{7}{2 \times 6} = \boxed{ \red{ \frac{7}{12} }}$

$9) \frac{9}{10} \times \frac{2}{3} = \frac{3}{5} \times \frac{1}{1} = \frac{ 3\times 1}{5 \times 1} = \frac{3}{5 \times 1} = \boxed{ \red{\frac{3}{5} }}$

$10) \frac{6}{13} \times \frac{1}{5} = \frac{6 \times 1}{13 \times 5} = \frac{6}{13 \times 5} = \boxed{ \red{ \frac{6}{65} }}$
