Question

Resolver las siguientes igualdades con fracciones:
1.- 1/8 + 1/4 = 1/24 + 1/3

2.- - 1/6 - 3/4 = - 1/4 - 2/3

3.- 2/5 - 87/10 + 87/15 = - 5/2

4.- 9/4 - 1/5 + 6 = 5/4 - 9/20
Proceso completo de cada uno. Sin respuestas absurdas

Answer 1

Respuesta:

1-

[tex] \frac{1}{8} + \frac{1}{4} = \frac{1}{24} + \frac{2}{3} [/tex]

[tex] \frac{1 + 2}{8} = \frac{1 + 8}{24} [/tex]

[tex] \frac{3}{8} = \frac{9}{24} [/tex]

2-

[tex] \frac{1}{6} - \frac{3}{4} = \frac{1}{4} - \frac{2}{3} [/tex]

[tex] \frac{2 - 9}{12} = \frac{3 - 8}{12} [/tex]

[tex] - \frac{ 7}{12} = - \frac{5}{12} [/tex]

3-

[tex] \frac{9}{4} - \frac{1}{5} + 6 = \frac{5}{4} - \frac{9}{20} [/tex]

[tex] \frac{45 + 4 + 120}{20 } = \frac{25 - 9}{20} [/tex]

[tex] \frac{169}{20} = \frac{16}{20} [/tex]

[tex] \frac{169}{20} = \frac{4}{5} [/tex]
