Question

5.- Resuelve las siguientes sumas de fracciones:

1/3 + 1/4=
2/3 + 5/8=
2/5 + 1/3 + 2/15=
2/5 + 3/10 + 1/2=
1 4/5 + 1 3/4

Answer 1

Explicación paso a paso:

1/3 + 1/4 = 7/12

2/3 + 5/8 = 31/24

2/5 + 1/3 + 2/15 = 13/15

2/5 + 3/10 + 1/2 = 6/5

1 4/5 + 1 3/4 = 71/20

Los resolví con el método de la mariposa :D

Answer 2

Respuesta:

$\frac{1}{3} +\frac{1}{4} =\frac{4+3}{12} =\frac{7}{12}$

$\frac{2}{3} +\frac{5}{8} =\frac{16+15}{24} =\frac{31}{24}$

$\frac{2}{5} +\frac{1}{3} =\frac{6+5}{15} =\frac{11}{15}+\frac{2}{15} =\frac{13}{15}$

$\frac{2}{5} +\frac{3}{10}=\frac{20+15}{50}+\frac{35}{50}+\frac{1}{2}=\frac{70+50}{100}=\frac{120}{100}$

$1\frac{4}{5} +1\frac{3}{4} =\frac{16+15}{20}=\frac{31}{20}+1+1=2 \frac{31}{20}$
