Fajnie by było, gdyby były też obliczenie, a nie sam wynik. Nie musicie robić wszysktich, zróbcie tyle ile dacie radę, z góry dzięki, obiecuję, że dam najkę. ;)

Answer 1

(5i5/6+4,5*1i2/3) :4i4/15= (5i5/6 + 4i1/2 *1i2/3) :64/15= (5i5/6 + 9/2 *5/3):64/15=

= (5i5/6 + 45/6): 64/15= 5i50/6 : 64/15 = 80/6 *15/64= 10/2*5/8 = 50/16= 3 i1/8

 

3i4/9 - 1i2/3 *1,8 = 3i4/9 - 5/3 * 1i4/5= 3i4/9 - 5/3* 9/5 =3i4/9- 45/15=3i4/9-3= 4/9

 

3/20 -(15*0,14 :1,5 -8,3 *0,1) * 0,5= 0,15 -(2,1 :1,5 - 0,83) *0,5= 0,15-(1,4-0,83) *0,5=

= 0,15 -0,57* 0,5= 0,15 -0,285 = -0,135

 

1i5/9 : 1i1/3 * 0,75 = 14/9 : 4/3 *3/4= 14/9 * 3/4 *3/4= 126/144= 14/16 = 7/8

 

5,1 *(0,6- 2/5 *0,5)= 5,1 *(0,6 -0,4 *0,5)= 5,1*(0,6 -0,2)= 5,1* 0,4 = 2,04

 

(1,9 + 1/9 )* 10= (19/10 +1/9) *10= (171/90 + 10/90)* 10=181/90 *10= 181/9*1=

= 181/9 = 20 i1/9

 

(4i2/3 +3,5)*(1,5 +4i1/14) = (4i2/3 +3i1/2) *(1i1/2 +4i1/14)= (4i4/6 +3i3/6)*

*(1i7/14 +4i1/14)=  7i7/6 * 5i8/14 = 49/6*78/14= 7/1 *13/2= 91/2=45i1/2

 

(4,6 - 2i1/2) :(4i3/5 +2,5)= (4,6 - 2,5) :(4,6+2,5)= 2,1 :7,1= 0.30

 

1i1/2:(1i1/4 : 1i1/3) : 1i1/5= 3/2 :(5/4: 4/3) :6/5= 3/2 :(5/4*3/4) :6/5 =

= 3/2:15/16 :6/5 = 3/2 *16/15 *5/6 = 240/180= 1i60/180= 1i1/3

 

10,4 -5i5/7 : 2 = 10,4 - 40/7 *1/2 = 10,4 -20/7 *1/1=104/10 -20/7=

= 728/70 - 200/70 = 528/70 = 7i38/70= 7i19/35

 

2i6/11 : 7/11 : 3,4= 28/11 * 11/7  : 3i2/5= 4/1 * 1/1 : 17/5=4*5/17= 20/17

 

(3,2 +7i1/3 +4i1/6) :2 = (3i1/5 +7i1/3 +4i1/6) :2 = (3i6/30 +7i10/30 +4i5/30) :2=

= 14i21/30 :2/1 = 14i7/10 * 1/2= 147/10 *1/2= 147/20= 7 i 7/20

 

0,9 : 1/5 + 1/3 - 3/5 = 9/10 *5/1 +5/15 -9/15 = 9/2*1 -4/15= 135/30- 8/30=

= 127/30 = 4i7/30

 

(2,2 -1i2/3) *10 = (2i1/5 - 1i2/3) *10 = (2i3/15 -1i10/15)*10= (1i18/15 -1i10/15)*10=

= 8/15 * 10 = 80/15 = 5i5/15= 5i1/3

 

6i2/3* (0,25 +1/5)= 20/3 *(0,25 +0,2)= 20/3 *0,45= 20/3 *45/100=1/1*15/5=15/5=3

 

(7,3 -1/2 *0,8) : 0,03= (7,3 - 0,5 *0,8): 0,03= (7,3 -0,4): 0,03= 6,9:0,03=690:3= 230
