Answer 1

Respuesta:

a. $\frac{3}{4} +\frac{5}{6} = \frac{3x3+5x2}{12} =\frac{9+10}{12} =\frac{19}{12} = 1\frac{7}{12}$

b. $\frac{7}{10} +\frac{7}{15} =\frac{7x3+7x2}{30} =\frac{21+14}{30} =\frac{35}{30} =\frac{7}{6} =1\frac{1}{6}$

c. $\frac{3}{4} +\frac{5}{8} =\frac{3x2+5}{8} =\frac{6+5}{8} =\frac{11}{8} =1\frac{3}{8}$

d. $\frac{5}{2} +\frac{1}{6} =\frac{5x3+1}{6} =\frac{15+1}{6} =\frac{16}{6} =\frac{8}{3} =2\frac{2}{3}$

e. $\frac{7}{6}+ \frac{9}{2} =\frac{7+9x3}{6} =\frac{7+27}{6} =\frac{34}{6} =\frac{17}{3} =5\frac{2}{3}$

Answer 2

Respuesta:

Explicación paso a paso:

a) $\frac{18+20}{24} = \frac{38}{24}$ = 1 $\frac{14}{24}$

b)$\frac{105+70}{150} = \frac{175}{150}$ = 1 $\frac{25}{150}$

c)$\frac{24+20}{32} = \frac{48}{42} = 1 \frac{6}{42}$

d) $\frac{30+2}{12} = \frac{32}{12} = 2\frac{8}{12}$

e) $\frac{14+54}{12} = \frac{68}{12} = 5\frac{8}{12}$
