Answer 1

jezu wiecej nie było ;O ale ok :)

 

/3+ 3/4= 4/12 + 9/12=14/12=1i2/12=1i1/6

2/3+5/7=14/21+15/21=29/21=1i2/21

5/6+4/9=454/54+24/54= 69/54= 1i 15/54

5/8+7/10= 50/80+56/80=106/80= 1i26/80= 1i 13/40

2i3/4+1/3= 11/4+ 1/3=32/12+4/12= 37/12= 3o 1/12

6i8/9 +2i1/10= 62/9+ 21/10= 620/90+189/90=809/90=8i89/90

2i7/9+ 3i5/6= 25/9+ 23/6= 150/54+207/54= 357/54= 6i33/54

2i9/10 + 3i7/15= 29/10 + 52/15= 435/150+ 520/150= 955/150= 6i55/15-= 6i11/30

3/4- 2/5= 15/20-8/20= 7/20

5/8-2/5=25/40-16/40=9/40

3/4-1/6=18/34-4/24=14/24=7/12

1i5/6-3/8=11/6-3/8=99/48-18/48=70/48=1i22/48=1i11/24

5i7/9 - 1i1/2=52/9-3/2=104/18-27/18=77/18=4i5/18

8i1/6-2i2/5=29/6-12/5=245/30-72/30=172/30=5i23/3-

5i1/4-1i1/6=21/4-7/6=126/24-28/24=98/24=4i2/24=2i1/12

8i3/4-2i7/10=35/4-27-10=350/40-108/40=242/40=6i2/40=6i1/20
