Rounding Off Data:

A process in which any mathematical value is simplified by decreasing the Number of significant figures is called “Rounding off Data”.

Rules for Rounding Off Data:

1.            If the figure to be removed is less than 5 then it is replaced by Zero.

753 ——–> S.F = 3

750 ——–> S.F =2

2.            If the figure to be removed is greater than 5 then it is replaced by 1 to its previous figure, e.g

1-            96734    ——–> S.F = 5                             97000    ——–> S.F = 2

2-             756 ——–> S.F =3                              760 ——–> S.F =2

3.            If the figure to be removed equal to 5 then its remove by making its previous figure as even.

735 ——–> S.F = 3

740 ——–> S.F = 2
