Answer 1

3/8 +5/12= 9/24 + 10/24= 19/24

 

5/6 -9/10= 25/30 - 27/30= -2/30 = -1/15

 

1/2 +3/4 +5/6= 6/12 +9/12 +10/12= 25/12= 2i1/12

 

13/16 - 3/4= 13/16 - 12/16 = 1/16

 

5/6 -5/8= 20/24 - 15/24= 5/24

 

2/3 -3/5= 10/15 - 9/15= 1/15

 

7/10 - 13/15= 21/30 - 26/30= -5/30 = -1/6

 

3/8 -3/5 + 7/10= 15/40 - 24/40 + 28/40= 43/40 -24/40=19/40

 

3i1/6 - 2i5/12= 3i2/12 - 2i5/12= 2i14/12 -2i5/12 = 9/12= 3/4

 

11i5/12 -5i11/18 = 11i15/36 - 5i22/36= 10i51/36 - 5i22/36= 5i29/36

 

3i5/6 -1i3/8= 3i20/24 - 1i9/24= 2i11/24

 

4i3/5 -4i1/15 = 4i9/15 - 4i1/15= 8/15
