The one who eats the $10 dinner pays 10/26 of $16 and the other pays 16/26 of $16.

"Buy one, get one free" means the $10 dinner is free. So, the total for both meals is $16. To split it fairly between two people, divide $16 by 2 people. That's $8 per person.
OR
Add up what the bill should have cost: $10 + $16 = $26. Then, 10/26 would be 38% and 16/26 would be 62%. So, 38% of the real total cost is $6.08 (for the person who bought the $10 dinner) and 62% is $9.92 (for the person who bought the $16 dinner).

This isn't really a math question so much as a judgement call. If they both pay $8, then the person with the $16 meal got his for half price while the other person paid 80% of the cost of his meal. If that seems fair, then so be it.
If the $16 person pays $11 and the $10 person pays $5, then they both save $5.
Your call.

If they are good friends - $8 each
Otherwise do what zprime said 10/26 of $16 and 16/26 of $16

You could say that one pays 10/26 of the bill and the other pays 16/26 of it. Multiply $16 by these fractions to see what each pays.
$9.85 and$6.15

$16 / 2 = $8 each.

16/26 times 16 = 9.85
10/26 times 16 = 6.15

the friend who ate the $16 will pay $10 and the friend who ate the $10 dinner pay $6.

Let us call the value of there dinners V
V1=16
V2=10
ratio v1:v2= 1.6:1
total cost =16
total v=26
16/26=0.6154
16x0.6154=$9.85
10x0.6154=6.15

The person should have ordered a $ 16.00 dollar dinner since it was free.
