i need some math help here. i'm trying to do some fraction addition and some of it i figured out but this is what i'm struggling with...
first off lemme tell you WHAT i'm doing...
i'm trying to calculate how many ounces of formula my newborn daughter had over the course of yesterday to see if she'd gotten the total 20 oz the doc wants her to get every day. (she's been having eating issues resulting in dramatic weight loss and dehydration landing her in a childrens hospital for 2 days...not fun.) and we are on strict doctor's orders that our daughter is to receive no less then 20 oz p/day if we can help it. so here's the total oz. p/feeding she took throughout the day & night yesterday...and then i'll tell you where i'm having the problem...
1 1/2
2
1
1 2/3
1
1 1/2
1/2
2
2

so far i was able to add the whole #'s and i got 11, then i added 2 of the 1/2's for another whole bringing that whole # up to 12. that left a 1/2 and the 2/3...so the math problem for me now is
12 1/2 + 2/3.
that 2/3 is my problem. i tried calculating it online and i got alot of something about uncommon denominators and changing them and i'm like
"huh?! "
the only thing i can do with fractions is adding the whole #'s and adding the simple fractions like the 1/2's to make whole #'s but that rogue 2/3 is throwin' me off and the computer couldnt even help me out.
now, from looking at those #'s it's blatantly obvious that my daughter did not get the 20 oz. the doctor wants her to get. we've got alot of issues with her taking just enough to satisfy her stomach and then clamping up tighter then a clam and at that point it's impossible to get more in her without forcing it, which we're really not comfortable doing.
this is my 1st time with a difficult eater, my other 2 kids were pirahnas at birth pounding down 2-3 oz right off with my oldest daughter taking 4 oz by 1-2 months of age.
so anyways, if you can help me figure out that 12 1/2 + 2/3 that'd be great. it looks to me like the total is gonna be somewhere in the 13-13 1/2 range.
