Answer 1

Respuesta:

Esperame que esta larga

Explicación paso a paso:

1) $\frac{1.2+1}{2} :\frac{3}{2} \\\frac{3}{2}-\frac{7}{2}+\frac{3}{2}\\ \frac{3-7+3}{2} \\\frac{-1}{2} \\ \frac{1}{2}$

2) $\frac{2.4+1}{4} : \frac{9}{4} \\Minimo comun multiplo 4,5,2:20\\\frac{45}{20} +\frac{16}{20} -\frac{30}{20} \\\frac{45+16-30}{20} \\\frac{31}{20} \\convertir las fracciones propias en numeros mixtos\\\\1\frac{11}{20}$

3)$\frac{1}{1} +\frac{3}{2}-\frac{9}{5}\\\\Minimo comun multiplo 1,2,5:10\\\frac{10}{10}+\frac{15}{10}- \frac{18}{10} \\\frac{10+15-18}{10} \\\frac{7}{10}$

4)$Minimo- comun- multiplo 3,6,2:6\\\frac{16}{6}-\frac{7}{6}-\frac{3}{6} \\\frac{16-7-3}{6} \\\frac{6}{6}\\ 1$

5)$-\frac{1}{9} . \frac{1}{4} \\-\frac{1.1}{9.4} \\\frac{1}{9.4} \\-\frac{1}{31} \\EL-PUNTO-ES- MULTIPLICAR$

6)$\frac{2}{5} .\frac{3}{-4}\\ \\\frac{2}{5}(-\frac{3}{4})\\-\frac{2}{5}.\frac{3}{4}\\\\\frac{1}{5}.\frac{3}{2}\\\\-\frac{1.3}{5.2} \\\frac{3}{5.2}\\\\-\frac{3}{10}$

7)$\frac{7}{5}.\frac{6}{2},\frac{1}{3}\\\\ \frac{7}{5} .\frac{3}{1} .\frac{3}{1}\\\\\\\frac{7.3.1}{5.1.3} \\\\\frac{7.1}{5.1} \\\\\frac{7}{5}\\LA , ES DIVISION$

8)$\frac{8.5.9}{15.4.6} \\\\\frac{120}{15.4.6} \\\\\frac{120}{120} \\\\1$
