0.267,0.24,0.275,0.214,0.23

#1 make sure each decimal has three digits by inserting a zero(0) 
Hence 
0.267 , 0.240 , 0.275 , 0.214, 0.230

Drop the left hand zero and the decimal point
Hence 
267  , 240 , 275 , 214, 230 
Rearrange from smallest to biggest 
214, 230, 240, 267, 275 .

Replace the left hand zero and decimal point. 
0.214, 0.230, 0.240, 0267. 0/275. 
0.214, 0.23, 0.24, 0.267. 0.275     (Done!!!!).

Round to 2.d.p. 
0.21, 0.23, 0.24, 027, 0.28
