Since w = x + y + missing part
Since x = 0.9875 and y = 0.675, then
You should add 0 to 0.675 to be 0.6750 because the other number has 4 decimal places to do the addition correctly
Since we do not know the value of the missing part, but we know that it will add to 1.6625, so the answer must be greater than 1.6625
