- if a fraction is = 5 if a fraction is = 5 - . it is recommend to round it round it . it is recommend to up to even value : : up to even value e.g., 6.3 35 = > 6.4 5 = > 6.4 e.g., 6. 6.4 45 = > 6.4 5 = > 6.4 6. . I t is more common or . I t is more common or acceptable to round it up round it up acceptable to e.g., 6.45 5 = > 6.5 ; = > 6.5 ; e.g., 6.4 4
