Question

Calcule as operações com fracao abaixo
A) 3/10+5/10

Answer 1

Resposta:

Explicação passo a passo:

a) $\frac{3}{10} +\frac{5}{10}$ $= \frac{8}{10} = \frac{4}{5}$

b) $\frac{1}{4} +\frac{3}{4}= \frac{4}{4} = 1$

c) $\frac{4}{6} -\frac{1}{5} = \frac{20}{30}- \frac{6}{30} =\frac{14}{30} =\frac{7}{15}$

d) $\frac{1}{4}+ \frac{3}{5}= \frac{5}{20} +\frac{12}{20} =\frac{17}{20}$

e) $\frac{2}{3} -\frac{1}{4} = \frac{8}{12}- \frac{3}{12} =\frac{5}{12}$

f) $\frac{3}{4} +\frac{2}{5} +\frac{5}{2} = \frac{15}{20}+ \frac{8}{20} +\frac{50}{20} = \frac{73}{20} =3\frac{13}{20}$

9. $\frac{5}{2} -\frac{1}{5}+ \frac{3}{4} =\frac{50}{20}- \frac{4}{20}+ \frac{15}{20} =\frac{61}{20} = 3\frac{1}{20}$

Espero que te ajude!! Bons estudos ;))
