Row percentage is calculated by dividing the numerical value of any particular cell in the row by the sum of all the values in that row and multiplying it by 100. This shows what proportion of the total value of row represented by that cell.
The row percentage between "Low" and "Value" shown with question mark in the table below can be calculated as - 84/64+84×100 = 84/148×100 =56.76%
Or you can write it as 57% according to the given instructions.
