"La pereza nos gana" ok no...

Resolución:

Ejercicio 1

2. $\frac{(+8)(-9)}{(-3)} = \frac{-72}{-3} = 24$

3. $\frac{(+4)(-5)}{(+2)}=\frac{-20}{+2} = -10$

4. $\frac{(+12)(-4)}{(+3)} =\frac{-48}{+3}= -16$

5. $\frac{(-8)(-5)}{(-4)}=\frac{40}{-4}= -10$

6. $\frac{(-15)(-6)}{(-5)}=\frac{90}{-5}=-18$

7. $\frac{(+6)(-9)}{(-3)}=\frac{-54}{-3} = 18$

8. $\frac{(-14)(-3)}{(-7)}=\frac{42}{-7} =-6$

9. $\frac{(-10)(-5)}{(-2)}=\frac{50}{-2}=-25$

10. $\frac{(+16)(-2)}{(+8)} =\frac{-32}{8} =-4$

Ejercicio 2

2. $\frac{[(-3).(+8)]+[(-5)(+3)]}{(-13)} =\frac{(-24)+(-15)}{(-13)} =\frac{-39}{-13} = 3$

3. $\frac{[(+4).(-5)]+[(-6).(-3)]}{(+19)}=\frac{(-20)+(+18)}{(+19)}=\frac{-2}{19}$

4. $\frac{[(-8).(-4)]+[(+8).(-6)]}{(-10)}=\frac{(+32)+(-48)}{(-10)}=\frac{-16}{-10} =\frac{8}{5}$

5. $\frac{[(-9).(-3)]+[(-9).(-8)]}{(+11)}=\frac{(+27)+(+72)}{(+11)}=\frac{99}{11}=9$

6. $\frac{[(+3).(-8)]+[(-4).(-10)]}{(-8)}=\frac{(-24)+(+40)}{(-8)}=\frac{16}{-8} =-2$

7. $\frac{[(-4).(+9)]+[(-11).(+2)]}{(-2)}=\frac{(-36)+(-22)}{(-2)}=\frac{-58}{-2}= 29$
