You know that one kitten weighs 2 lbs 4 oz. and the other ways 2 lbs 2 oz all you need to do is add that together to get 4 lbs 6 oz then convert that into lbs (1 lbs = 16 oz)
In total the 4 lbs gets you 64 oz, then you just need to add the 6 remaining oz to get 70 lbs!
<h3>All you have to do is subtract the 2 oz from the 2 lbs 4 oz which = to 2 lbs 2 oz(which is the second kitten).</h3><h3>Then you have to add 2 lbs 2 oz with 2 lbs 4 oz. And then you get your answer(4 lbs 6 oz)!!!!!!!!!!!!</h3><h2>I hope this helped you very much!!!!!!!!!!!!!!</h2>
