Work Step by Step
The statement does not make sense.
In Jefferson's method, a modified divisor is used which is slightly less than the standard divisor. This modified divisor is used to find each state's modified quota. Then each state's modified quota is rounded down to the nearest whole number.
In Adams's method, a modified divisor is used which is slightly more than the standard divisor. This modified divisor is used to find each state's modified quota. Then each state's modified quota is rounded up to the nearest whole number.
We can see that the mathematics required in each method is essentially the same.
