Analysis shows that nickel oxide has the formula ni 0.98 o1.00. What fractions of nickel exist as ni 2+ and ni 3+ ions?

Given formula is Ni0.98O1.0
 
the ratio of Ni : O = 98 : 100 which means for 100 atoms of oxygen there are 98 atoms of nickels are present.
 
Let us consider the number of atoms of Ni2+ = x hence  the number of atoms of Ni3+ = 98 - x
 
Charge on Ni = charge on O 
3(98-x) + 2x = 2(100)
 
294 - 3x + 2x = 200
-x = -94
x = 94
 
 
Percentage space of space Ni to the power of 2 plus end exponent space equals space fraction numerator atoms space of space Ni to the power of 2 plus end exponent space over denominator Total space number space of space atoms space of space Ni end fraction space cross times space 100 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 94 over 98 cross times 100 space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals space 96 space percent sign
 
 
Percentage of Ni+3 = 100 - Ni2+
                            = 100 - 96
                            = 4 %

sir in types of unit cell we studied it can be of 4 types i.e primitive, face centred, body centred and end centred, but while studing 3D close packing it was told that it can be of 3 types i,e. simple(primitive) cubic unit cell, hcp and ccp. but i am not able  to understand that hcp is a type of unit cell or it is one of the 7 crystal system or somthing else?and if it is type of unit cell then why it is not taught under the topic types of unit cell. and if it is a crystal system then what about the rest 6 crystal system, then why rest 6 crystal system does not comes under 3 dimensional close packing?
