Hola me podrían ayudar a resolver esto quien lo resuelva bien le doy los puntos

Answer 1

Respuesta:

Espero que te sirva :)

Explicación paso a paso:

a)

$\frac{1}{5}.(\frac{1}{2}+\frac{1}{3})=\frac{1}{5}.(\frac{2+3}{6})=\frac{1}{5}.(\frac{5}{6})=\frac{5}{30}=\frac{1}{6}$

b)

$\frac{\frac{1}{10}}{(\frac{2}{3}-\frac{3}{5}) } =\frac{\frac{1}{10} }{\frac{2.5-3.3}{15} }=\frac{\frac{1}{10} }{\frac{10-9}{15} }=\frac{\frac{1}{10} }{\frac{1}{15} }=\frac{15}{10}=\frac{3}{2}$

c)

$(\frac{2}{3}-\frac{1}{2})(\frac{1}{3}-\frac{1}{5})=(\frac{2*2-1*3}{6})(\frac{1*5-1*3}{15})=(\frac{4-3}{6})(\frac{5-3}{15})=(\frac{1}{6})(\frac{2}{15})=\frac{1*2}{6*15}=\frac{2}{90}=\frac{1}{45}$

d)

$[-13+(24-68)]-(-48+95)=[-13+(-44)]-(47)=[-13-44]-47=-57-47=-104$

e)

$48-[12-(43-38)-27]=38-[12-(5)-27]=38-[12-5-27]=38-[-20]=38+20=58$

f)

$32-[19-(24-46)]=32-[19-(22)]=32-[19-22]=32-[-3]=32+3=35$

g)

$(24-89+18)+(-91+24)=-47+(-67)=-47-67=-114$
