Question

a 1,2+5/6= b 4,8-1 1/3= c 33,3+1/3-1,25= d 2,25-1 1/3-1,5=

Answer 1

a) 1,2 +5/6= 1i1/5 + 5/6= 1i6/30+ 25/30= 1i31/30 = 2i1/30

 

b) 4,8 -1i1/3 = 4i4/5 - 1i1/3= 4i12/15 -1i5/15 = 3i7/15

 

c) 33,3 + 1/3 -1,25 = 33i3/10 +1/3 -1i1/4= 33i18/60 +20/60 -1i15/60= 32i23/60

 

d) 2,25 -1i1/3-1,5= 2i1/4-1i1/3-1i1/2= 2i3/12-1i4/12-1i6/12= 2i3/12- 2i10/12= -7/12
