I had Fifth disease when I was, oddly enough, in the fifth grade. It's just a virus with symptoms that include a rash (I remember it was on my face) and I think a fever and it lasts a couple of weeks or so. I got over it with no problems, as I think most kids do.
2 and 2 5ths... its really not that hard...
7 and 2/5ths
4 5ths
9 5ths is equal to 9x5=45
12/5
12/5ths = 2 and 2/5ths 2 and 2/5ths - 1 = 1 and 2/5th
4 and 2 5ths = 22/5 2 and 3 5ths = 13/5 22/5 + 13/5 = 35/5 = 7/1 = 7
There are an infinite number of fractions less than 4/5ths, such as 3/5ths, 2/5ths, and 1/5th.
3 5ths+3 fourths=17 20ths
1 and 2 5ths would be 7/5
Are you asking how many 1/5ths there are in 1 whole? If so, there are 5.
to find the decimal of four 5ths you have to divid 4 over 5 and you get =1.25
