# CLASS-5ROUNDING OFF DECIMAL FRACTION TO NEAREST WHOLE NUMBER

Rounding Off A Decimal Fraction To The Nearest Whole Number -

For rounding off the decimal fraction to the nearest whole number, we see the digit in the tenths place. If it is less than 5 (i.e. 1, 2, 3, 4), the digit in the ones place remains the same. If the digit in the tenths place is 5 or more than 5 (i.e. 5, 6, 7, 8, 9), we add 1 to the digit in the ones place.

Examples -

i) Round off 88.4582 to the nearest whole number. -

We look at the digit in the tenths place (i.e. immediately after the decimal). In 88.4582 since 4 < 5, the nearest whole number to 88.4582 will be 88

ii) Round off 714.806 to the nearest whole number. -

We look at the digit in the tenths place (i.e. immediately after the decimal). In 714.806 since 8 > 5, the nearest whole number to 714.806 will be 715

Round off the following as instructed :-

a) To the nearest meter :-

19.67 m

We look at the digit in the tenths place (i.e. immediately after the decimal). In 19.67 m since 6 > 5, 19.67 m round off to the nearest meter will be 20 m.

b) To the nearest liter :-

3.467 l

We look at the digit in the tenths place (i.e. immediately after the decimal). In 3.467 l since 4 < 5, 3.467 l round off to the nearest liter will be 3 l.

c) To the nearest kg :-

4.576 kg

We look at the digit in the tenths place (i.e. immediately after the decimal). In 4.576 m since 5 = 5, 4.576 kg round off to the nearest kg will be 5 kg.
