Answer 1

Respuesta:

a) Solución:

$=\frac{2}{3}\cdot \frac{3}{4}+\frac{5}{6}$

$=\frac{1}{2}+\frac{5}{6}$

$=\frac{3}{6}+\frac{5}{6}$

$=\frac{3+5}{6}$

$=\frac{8}{6}$

$\boxed {=\frac{4}{3}}$

b) Solución:

$=\frac{3}{8}+\frac{2}{3}\cdot \frac{6}{10}+\frac{-7}{20}$

$=\frac{3}{8}+\frac{2}{5}-\frac{7}{20}$

$=\frac{15}{40}+\frac{16}{40}-\frac{14}{40}$

$=\frac{15+16-14}{40}$

$\boxed {=\frac{17}{40}}$

c) Solución:

$=\frac{5}{9}+\frac{3}{8}\div \frac{3}{11}$

$=\frac{5}{9}+\frac{3}{8}\times \frac{11}{3}$

$=\frac{5}{9}+\frac{11}{8}$

$=\frac{40}{72}+\frac{99}{72}$

$=\frac{40+99}{72}$

$\boxed {=\frac{139}{72}}$

d) Solución:

$=\frac{5}{12}\div \frac{3}{4}\frac{-4}{5}$

$=\frac{5}{12}\times \frac{4}{3}\times \frac{-4}{5}$

$=\frac{5\times \:4\left(-4\right)}{12\times \:3\times \:5}$

$=\frac{4\left(-4\right)}{12\times \:3}$

$=\frac{-4\times \:4}{12\times \:3}$

$=\frac{-16}{36}$

$\boxed {=-\frac{4}{9}}$

e) Solución:

$= \frac{\frac{5}{6}-\frac{3}{4}}{\frac{7}{12}+\frac{1}{3}}$

$=\frac{\frac{1}{12}}{\frac{11}{12}}$

$=\frac{1\cdot \:12}{12\cdot \:11}$

$=\frac{12}{12\cdot \:11}$

$\boxed {=\frac{1}{11}}$

f) Solución:

$=\frac{2-\frac{1}{2}}{3+\frac{1}{3}}$

$=\frac{\frac{3}{2}}{\frac{10}{3}}$

$=\frac{3\cdot \:3}{2\cdot \:10}$

$=\frac{3\cdot \:3}{20}$

$=\frac{9}{20}$
