Answer 1

1) 77 i 1/7 + 3 i 5/14 = 77 i 2/14 + 3 i 5 14 = 80 i 7/14 = 80 i 1/2

2) 66 i 1/6 - 4 i 5/6 = 397/6 - 29/6 = 368/6 = 61 i 2/6 = 61 i 1/3

3) 2 i 1/2 * 1 i 3/5 = 5/2*8/5 = 40/10 = 4

4) 7 i 2/3 : 1 i 1/2 = 23/3 : 3/2 = 23/3 *2/3 = 46/9 = 5 i 1/9

Answer 2

1). 77i1/7 + 3i5/14= 77i2/14 +3i5/14= 80i7/14= 80i1/2

 

2). 66i1/6 -4i5/6= 65i7/6 - 4i5/6= 61i2/6= 61i1/3 

 

3) 2i1/2 * 1i3/5= 5/2 * 8/5= 1/1 *4/1= 4

 

4) 7i2/3 :1i1/2= 23/3 :3/2= 23/3 * 2/3= 46/9= 5i1/9
