If you're making an equation for 10 siblings to evenly share a pizza which is cut into 6 slices, what would be the best equation if X = 1 slice? (Algorithm)

Question

This is more math based but I got this question for a computer science assignment. Can someone explain to me? These are the answers given. I can't wrap my head around it.

A. (5X/2)+(X/10)

B. X/10

C. 5(X/2)+(X/10)

D. (X/10)+6

Answer 1

Hmm, 10 ppl eating 6 slices of pizza evenly would be 6 slices per 10 people, or 6/10, x slices = 6.

If x = 1 slice, then it's simply 1 slice per 10 people, or x/10, i.e. the pizza is one whole slice, or not cut (that's my interpretation of the question).

Answers A and C are identical. The wording is obfuscated.
