BAB
so Barb (D12HD) =+1/lvl BAB, and Ranger (D8HD) =+3/4 /lvl BAB
Therefore Kubo BAB = 1 + (3/4*3) = 1 + 2.25 = 3.25 or 3 rounded down [OoC:is that right?]
Saves
Fort = Barb =(Good or +1/2/lvl), Ranger = (Good or 1/2/lvl) = 1/2 (Barb) + (1/2*3(Ranger))= .5+1.5= 2 +3(Con) = 5
REF = Barb= (Poor or 1/3/lvl), Ranger = (Good or 1/2/lvl) = 1/3 (Barb) + (1/2*3(Ranger)) = 1/3 + 1.5= 1.83 rounds to 2 = 2+4(DEX)=6
WIL = Barb = (poor or 1/3/lvl), Ranger = (Poor or 1/3/lvl) = 1/3 (Barb) + (1/3*3(Ranger))= 1/3*4 = 1.33 rounds to 1 +1(Wis) = 2
[OoC:Ihope my math is correct]
Your BAB won't change. Both classes have Good Attack bonuses. So Barbarian 1 + Ranger 3 = +4 BAB
It's your saves where you MIGHT see a change.
Fortitude: Barbarian Good + Ranger Good
Reflex: Barbarian poor + Ranger Good
Will: Barbarian poor + Ranger Poor
Fortitude: Bar 2.5 + Ran 3.5 = 6 + Con 3 = 9
Reflex: Bar 1/3 + Ran 3.5 = 3 (3.83333333333) + Dex 4 = 7
Will: Bar 1/3 + Ran 1 = 1 (1 and 1/3) + Will 1 = 2
Unfortunately there isn't any change between just adding both classes together and the Fractional system. That doesn't mean there won't be a change at later levels like there was for Tomeal.
In Kubo's case, just adding the Fortitude bonuses together would give him a +5 (+8 with con). But using Fractional bonus his Fortitude is bumped up by one to +6 (+9 with con). Reflex and Will doesn't change.
A example of the fractional system to show why it's needed is, lets say you multi-class as a Cleric 1, Rogue 1, Wizard 1, Druid 1. (It's ridiculous but stay with me.) That character would still have a BAB +0 even though he's a 4th level character. Using the fractional system his BAB would be 2.75 (round down to +2). If he were to add another class such as Scout his BAB would be (2.75 + 0.75 = 3.5) +3 rather than +0. So depending upon your build, it can really help you out.
RE Feats: You gain a bonus Feat every odd Character level instead of every 3 levels like you would by normal rules. You are a 4th level character so you won't gain a feat until you gain 1 more level in any class.
