Urgent, quick reply awaited! - Solid State

For fluorite structure, it is given that co.no. for Ca is 4 and for F is 8.

How do we rep. the coordination no. for the entire structure?

Is it 4:8 or 8:4?

No. of Ca⁺²ions=4

No. of F^-ions=8

one Ca ion combines with 2 Fe ions.
So, number of CaF₂ ions=4.
