Verified answer

RESOLVER:

a) [tex]\frac{11}{5}\div \:0.2[/tex]

Para hacer más fácil el proceso, convertimos el decimal en fracción, entonces:

[tex]0.2=\frac{0.2}{1}[/tex]

[tex]=\frac{11}{5}\div \frac{0.2}{1}[/tex]

[tex]=\frac{11}{5}\times \frac{1}{0.2}[/tex]

[tex]=\frac{11\times \:1}{5\times \:0.2}[/tex]

[tex]\:11\times \:1=11[/tex]

[tex]=\frac{11}{5\times \:0.2}[/tex]

[tex]5\times \:0.2=1[/tex]

[tex]=\frac{11}{1}[/tex]

Ya!!, entonces quitamos el uno de abajo y nos queda el entero 11

[tex]\boxed{=11}[/tex]

b) [tex]1\frac{2}{9}\times \frac{11}{2}[/tex]

[tex]=\frac{11}{9}\times \frac{11}{2}[/tex]

[tex]=\frac{11\times \:11}{9\times \:2}[/tex]

[tex]11\times \:11=121[/tex]

[tex]=\frac{121}{9\times \:2}[/tex]

[tex]\:9\times \:2=18[/tex]

[tex]\boxed{=\frac{121}{18}}[/tex]

y en mixto sería [tex]=6\frac{13}{18}[/tex]
