Question

2/3+7/12 =?
1/4+8/4=?
4/5+5/6=?
4/7+6/7=?
12/16+14/16=?
4+1/3=?​

Answer 1

RESOLVER:

a) $\frac{2}{3}+\frac{7}{12}$

Buscamos el MCM de 3, 12 que es 12

Entonces:

$=\frac{8}{12}+\frac{7}{12}\\\\=\frac{8+7}{12}\\\\=\frac{15}{12}\\\\\boxed{=\frac{5}{4}}$Porque cancelamos

b) $\frac{1}{4}+\frac{8}{4}$

$=\frac{1+8}{4}\\\\\boxed{=\frac{9}{4}}$

c) $\frac{4}{5}+\frac{5}{6}$

El MCM de 5, 6 es 30

Entonces:

$=\frac{24}{30}+\frac{25}{30}\\\\=\frac{24+25}{30}\\\\\boxed{=\frac{49}{30}}$

d) $\frac{4}{7}+\frac{6}{7}$

$=\frac{4+6}{7}\\\\\boxed{=\frac{10}{7}}$

e) $\frac{12}{16}+\frac{14}{16}$

$=\frac{12+14}{16}\\\\=\frac{26}{16}\\\\\boxed{=\frac{13}{8}}$porque cancelamos

f) $4+\frac{1}{3}$

Convertimos el 4 a fracción: $\frac{12}{3}$

$=\frac{12}{3}+\frac{1}{3}\\\\=\frac{12+1}{3}\\\\\boxed{=\frac{13}{3}}$
