10
I could be wrong but I think it's 10.
Twenty fifths is 4 whole.
There are five fifths in one whole.
two-fifths of 4 = 1.6
Four fifths is not a whole number so it is not possible to express it as a whole number.
four fifths must be added to make it whole
5 fifths is one whole 5x 4 = 20 fifths = 4 wholes
One-fifth and four-fifths makes a whole.
12 and 4 fifths
No, four fifths is not larger than a whole. A whole is one, and 4/5ths is 4 parts out of 5, or 1 part out of 5 lessthan 1.
Four-tenths, or two-fifths.
4 and two fifths multiplied by three is 13 and 1 fifth.
