ayuda porfavor no entiendo :c​

Answer 1

$g)\frac{12}{5} - \frac{3}{5}$

$=\frac{12-3}{5}$

$=\frac{9}{5}$

$h) \frac{6}{2} - \frac{4}{2}$  → 6÷2 = 3 / 4÷2 = 2

= 3 - 2        

= 1

$i) \frac{10}{3} - \frac{6}{3}$

$=\frac{10-6}{3}$

$=\frac{4}{3}$

$j) 3\frac{1}{5} + 2\frac{1}{5} + \frac{5}{5} - \frac{15}{5}$

$=\frac{16}{5}+\frac{11}{5} + \frac{5}{5} - \frac{15}{5}$

$=\frac{16+11+5-15}{5}$

$=\frac{17}{5}$

$=3\frac{2}{5}$

$k)4\frac{2}{6} + 2\frac{4}{6} + \frac{36}{6} - \frac{2}{6}$

$=\frac{26}{6} + \frac{16}{6} + \frac{36}{6} - \frac{2}{6}$

$=\frac{26+16+36-2}{6}$

$=\frac{76}{6}$

$=\frac{38}{3}$

$=12\frac{2}{3}$

$l)5\frac{4}{9} + \frac{81}{9} + \frac{4}{9} - 3\frac{1}{9}$

$=\frac{49}{9} + \frac{81}{9} + \frac{4}{9} - \frac{28}{9}$

$=\frac{49+81+4-28}{9}$

$=\frac{106}{9}$

$=11\frac{7}{9}$
