Answer 1

Explicação passo-a-passo:

.

$\dfrac{1}{5} \times \dfrac{1}{2} \times \dfrac{4}{3}$

$\dfrac{4 \div 2}{30 \div 2}$

$\dfrac{2}{15}$

.

$\dfrac{5}{4} + \dfrac{1}{5} - \dfrac{3}{2}$

$\dfrac{25 + 4 - 30}{20}$

$- \dfrac{1}{20}$

.

$\dfrac{2}{5} \times \dfrac{3}{6} \times \dfrac{1}{3}$

$\dfrac{6 \div 6}{90 \div 6}$

$\dfrac{1}{15}$

.

$\dfrac{3}{7} \div \dfrac{7}{15}$

$\dfrac{3}{7} \times \dfrac{15}{7}$

$\dfrac{45 \div 5}{35 \div 5}$

$\dfrac{9}{7}$

.

$\dfrac{3}{5} \times \dfrac{3}{2} \times \dfrac{11}{3}$

$\dfrac{99 \div 3}{30 \div 3}$

$\dfrac{33}{10}$

.

$\dfrac{1}{5} + \dfrac{2}{5} + \dfrac{3}{5}$

$\dfrac{6}{5}$
