Question

Resolva as seguintes operação envolvendo fração:
1/2+4/5=
2/7_5/8=
14/5×6/7=
8/31×4/3=
7/5÷2/7=
9/5÷2/12=

Answer 1

RESPOSTA :

$\frac{1}{2} + \frac{4}{5} = \frac{6}{6}$

$\frac{2}{7} - \frac{5}{8} = \frac{6}{2}$

$\frac{14}{5} \times \frac{ 6}{7} = \frac{98}{30}$

$\frac{8}{31} \times \frac{4}{3} = \frac{122}{24}$

$\frac{7}{5} \div \frac{2}{7} = \frac{2.5}{1}$

$\frac{9}{5} \div \frac{2}{12} = \frac{0.75}{2.5}$
