Question

Oblicz:

5*(-2/11)-(-3)*4/3=

-(-1 1/2)-4 1/2-6(-3)=

4 2/3*(-2 1/4)-3 1/5*(-1/4)=

Answer 1

-10/11-(-4) = -10/11+4 = 3 i 1/11

1,5 - 4,5-6*(-3) = -3+18 = 15

mam nadzieję, że tu było mnożenie.

14/3*(-9/4)-16/5*(-1/4) TUTAJ SIĘ SKRACA 3 i 9.    4 Z 16 W DRUGIM RÓWNANIU

-21/2+2/5 = -105/10+4/10 = -101/10 = -10 i 1/10

Answer 2

5*(-2/11)-(-3)*4/3= -5*2/11-(-3)*4/3= -10/11-(-3)*4/3= -10/11-(-3*4/3)= -10/11-(-4)= -10/11+4=34/11

 

-(-1 1/2)-4 1/2-6(-3)= -(-3/2)-4 1/2-6(-3)=3/2-4 1/2-6(-3)=3/2-9/2-6(-3)= -3-6(-3)= -3-(-6*3)=

= -3-(-18)= -3+18=15

 

4 2/3*(-2 1/4)-3 1/5*(-1/4)=14/3*(-2 1/4)-3 1/5*(-1/4)=14/3*(-9/4)-3 1/5*(-1/4)=

= - 14/3*9/4-3 1/5*(-1/4)= -21/2-3 1/5*(-1/4)= -21/2-16/5*(-1/4)= -21/2-(- 16/5*1/4)=

= -21/2-(-4/5)= -21/2+4/5= -97/10
