Tanisha has 2 new kittens. Together they weigh 3 5/8 pounds. If the male kitten weighs 5/8 pound more than the female kitten, how much does the male kitten weigh?

female  x
male  x + 5/8
x + 5/8 = 29/8
8x + 5 = 29
you finish it, ok? 
Let female=x
male= 5/8+x
3 5/8 pounds is the same as 29/8 (this is the improper form, it's easier to write it this way).
x+5/8= 29/8
Subtract 5/8 on both sides (we do this to get the x by itself).
x= (29/85/8)= 24/8 which can be simplified down to 3
x=3
The male kitten weighs 3 pounds.
Hope this helps. 
Male + Female = 3 5/8
M + F = 29/8 (Normalized 3 5/8 to 29/8)
Male = Female + 5/8
M = F+5/8
Male which is 5/8 times Female plus Female is equal to 29/8
(F+5/8)+F=29/8
2F=29/85/8
2F=24/8
2F=3
F=3/2
F=1 1/2
So female weight is 1 1/2
Male weight = Female + 5/8
M=3/2 + 5/8
M = (24+10)/16
M=34/16
M=17/8 = 2 1/8
So Male weight = 2 1/8 lbs
Female weight = 1 1/2 lbs
