d)4/3-5/8= e)9/5-5/6=​

Answer 1

Resposta:

Olá!

Explicação passo-a-passo:

a. $\frac{5}{12} +\frac{5}{12} =\frac{10}{12} =\frac{5}{6}$

b. $\frac{6}{5} +\frac{4}{3}=\frac{18+20}{15}=\frac{38}{15}$

c.$\frac{7}{2} +\frac{5}{8}=\frac{28+5}{8}=\frac{33}{8}$

d. $\frac{4}{3} -\frac{5}{8}=\frac{32-15}{24}=\frac{17}{24}$

e. $\frac{9}{5} -\frac{5}{6}=\frac{54-25}{30}=\frac{29}{30}$
