Question

A) -8 1/18 -(-5 5/6)=
b) -4 5/6 + (- 8 3/8)=
c) 2 8/11 * (-1 19/15)
d) -2 1/4 : (-5 5/8)=
e) [ 1 1/4 + ( -2) do potęgi drugiej : 1 1/3] * (-2)=

Answer 1

A= -145/18-(-35/6)= -145/18+35/6= -20/9= -2 2/9
b= -29/6+(-67/8)= -29/6-67/8= -317/24= -13 5/24
c= 30/11*(-34/15)= -30/11*34/15= -68/11= -6 2/11
d= -9/4:(-45/8)= -(-2/5)=2/5
e= (5/4+4:4/3)*(-2)=(5/4+3)*(-2)=17/4*(-2)= =17/4*2= -17/2= -8 1/2

Answer 2

A) -8 1/18 -(-5 5/6)= -8 1/18+ 5 15/18=  -2 4/18= -2 2/9
b)-4 5/6+(-8 3/8)= -4 20/24- 8 9/24=-12 29/24= -13 5/24
c)2 8/11 *(-1 19/15)=30/11 *(-34/15)= -68/11= -6 2/11
d)-2 1/4:(-5 5/8)= -9/4 *(-8/45)=2/5
e)[1 1/4+(-2)^2:1 1/3]*(-2)=(1 1/4+4*3/4)*(-2)=(1 1/4+3)*(-2)=4 1/4*(-2)= -8,5
