So we have 810.9, we have 4.13.18.310.8 and 6.0. So what is the value, what is the PKA that is directly above this value of seven. So we have eight. We have ten point 910.88, .3 are all the values directly above it, and eight is the closest one to seven. So that means we basically use eight as one of those values, and then the one directly below it, we have 3.14.1 and 6.0. So we use this 6.0 value.
