The answer is 1/5. this is how you work it out: 1/5 x 1/1=1/5!
Hope this helps!
1 whole = 100 percent. 1 fifth = (1 whole)/5 = (100/5) = 20 percent.
One-fifth and four-fifths makes a whole.
1 whole and 1 fifth=11/5
1/5 (one fifth)
It is: 1/4 times 1/5 = 1/20
1/5
5, hence the term "one fifth"
2/25
4/5
It is: 1/2 times 1/5 = 1/10
24/5
Since five fifths equal one whole, 6/5 would equal one whole plus one fifth. So 7 plus 1 and one fifth is 8 and 1 fifth or 8 1/5
