Hi there, bascially decompose means two fractions that add up to 11/5. There are alot of ways to decompose 11/5 so I am only giving 3 ways to decompose 11/5.
The first way is 10/5+1/5, the second way is 9/5+2/5, and the third way is 6/5+5/5
67:938
But when you reduce this ratio your final answer is 1:14
