Question

me ayudan plises para el lunes​

Answer 1

Explicación paso a paso:

1.-

a. $\frac{2}{3} + \frac{1}{6} = \frac{2 \times 6 \: + \: 3 \times 1}{3 \times 6} = \frac{12 + 3}{18} = \frac{15}{18} = \frac{5}{6}$

b.

$\frac{4}{5} + \frac{3}{10} + \frac{2}{15} = \frac{4 \times 6}{5 \times 6} + \frac{3 \times 3}{10 \times 3} + \frac{2 \times 2}{15 \times 2}$

$\frac{24 + 9 + 4}{30} = \frac{37}{30}$

c.

$\frac{2}{4} + \frac{7}{12} + \frac{2}{3} = \frac{2 \times 3}{4 \times 3} + \frac{7}{12} + \frac{2 \times 4}{3 \times 4}$

$\frac{6 + 7 + 8}{12} = \frac{21}{12} = \frac{7}{4}$

2.-

$\frac{21}{6} = 3 \frac{1}{2}$

$\frac{30}{8} = 3 \frac{3}{4}$

$\frac{29}{9} = 3 \frac{2}{9}$
