The horizontal sums of the survey numbers are 200, so the numbers in the left chart are the survey values divided by 200.
The vertical sum in the first column is 188, so the first column of the right chart will be 76/188 and 112/188. Likewise, the vertical sum in the second column is 212, so the numbers will be 124/212 and 88/212.
Once you find the first number in each case, the second number is that value subtracted from 1, since the total of the two must be 1.
