Percentile Rank

Some are asking if tama ung formula my reference came from this

i think the formula of Grouped Data of Percentile should also be that way.

so the formula i think should be
Pr = n/100[P - LB)/i +cfp] not the one on our g10 math learners material Pr = n/100 + [P - LB)/i +cfp

go back on this example that came from the g10 math learners material and makikita niyo na mali ung problem kapag addition ang ginamit na formula mali din ung value ng fp dito instead of 27 dapat 11

Thank You!
