Question

Realizar las operaciones expresa los resultados de forma irreducible

Answer 1

2) $\frac{12}{5}\times \frac{11}{4}\times \frac{3}{10}$

$=\frac{12\times \:11\times \:3}{5\times \:4\times \:10}$

$=\frac{396}{5\times \:4\times \:10}$

$=\frac{396}{200}$

$=\frac{99}{50}$

3) $\frac{3}{15}\times \frac{7}{4}\times \frac{9}{28}$

$\frac{3}{15}=\frac{1}{5}$

$=\frac{1}{5}\times \frac{7}{4}\times \frac{9}{28}$

$=\frac{1\times \:7\times \:9}{5\times \:4\times \:28}$

$=\frac{63}{5\times \:4\times \:28}$

$=\frac{63}{560}$

$=\frac{9}{80}$

4)$\frac{32}{15}\times \:2\frac{1}{4}\times \frac{5}{18}$

$=\frac{32}{15}\times \frac{9}{4}\times \frac{5}{18}$

$=\frac{32\times \:9\times \:5}{15\times \:4\times \:18}$

$=\frac{1440}{15\times \:4\times \:18}$

$=\frac{1440}{1080}$

$=\frac{4}{3}$

$=1\frac{1}{3}$

5)$3\frac{3}{4}\times \frac{8}{11}\times \:2\frac{2}{5}$

$=\frac{15}{4}\times \frac{8}{11}\times \:2\frac{2}{5}$

$=\frac{15}{4}\times \frac{8}{11}\times \frac{12}{5}$

$=\frac{15\times \:8\times \:12}{4\times \:11\times \:5}$

$=\frac{1440}{4\times \:11\times \:5}$

$=\frac{1440}{220}$

$=\frac{72}{11}$

$=6\frac{6}{11}$
