Question

(1 1/3)3 * (-3 3/4)2 : 3 – (1/3)2 =

(-3 1/3)3 * 0,34 - (-1/2)3 * (1 1/3)2 =

Answer 1

(1 1/3)3 * (-3 3/4)2 : 3 – (1/3)2 =

(4/3)3 *(-15/4)2 :3 -(1/3)2=

64/27*225/16:3-1/9=

4/9*75/1::3-1/9= (było skracanie)

300/9*1/3-1/9=100/9-1/9=99/9=11

 

 

(-3 1/3)3 * 0,34 - (-1/2)3 * (1 1/3)2 =

(-10/3)3 *0,34 -(-1/8)*(4/3)2=

-1000/27*34/100+1/8*16/9=

-34/27+1/8*8/9= (znów skracanie)

-34/27+8/36=

-34/27+2/9= (skracanie)

-34/27+6/27=

-28/27= - 1 i 1/27
