Divide one column by another in a matrix

Hi alexstock01 
You can create 3 needed measures.
For example, my table looks like :

So the measures will be:
1.Credit = CALCULATE(sum('Table'[Value]),'Table'[type]="credit")

2. 

Debit = CALCULATE(sum('Table'[Value]),'Table'[type]="debit")

3. 

ROI = DIVIDE([Debit],[Credit])

pbix is attached you can follow my steps
