me ayudan con los resultados​

Answer 1

1

$\frac{2}{7} + \frac{1}{7} + \frac{5}{7} \\ \frac{8}{7}$

2.

$\frac{12}{7} + \frac{1}{3} \\ \\ \frac{12 \times 3 + 7 \times 1}{21} \\ \frac{36 +7 }{21} = \frac{42}{21} = 2$

3.

$\frac{21}{9} + \frac{11}{8} \\ \frac{21 \times 8 + 9 \times 11}{72} \\ \frac{168 + 99}{72} \\ \frac{267}{72}$

4.

$\frac{4}{5} + \frac{9}{2} \\ \frac{4 \times 2 + 9 \times 5}{10} \\ \frac{8 + 45}{10} \\ \frac{53}{10}$
