Rounding off Decimal FractionsRounding off decimal fractions can also be rounded off to the nearest one to one place of decimal or to two places of decimals or as is required.
(i) 32.2 can be rounded off 32 (ii) 46.8 can be rounded off 47 (iii) 188.9 can be rounded off 189 (iv) 59.1 can be rounded off 59 (v) 170.2 can be rounded off 170 Sally bought a pair of shoes; the cost of a pair of shoes would probably read as $ 249.95. But she paid $ 250, i.e., $ 249.95 has been rounded off to $ 250. Kelly bought a pair of shirts; the cost of a pair of shirts would probably read as $ 143.22. But she paid $ 143, i.e., $ 143.22 has been rounded off to $ 143. Nearest 1 While rounding off a decimal fraction to the nearest one, if the digit in the tenths place is < 5 then the tenths place and the entire following place replace by 0. If the tenths place is equal to or > 5 then the digit in the ones place is increased by 1 and all digits after the decimal are reduced to 0. For Example: Round off to the nearest one (units place) (i) 49.37 → 49.00 Since 3 < 5 (ii) 96.872 → 97.00 Since 8 > 5 (iii) 67.437 → 67.000 Since 4 < 5 (iv) 9.909 → 10.000 Since 9 > 5 (v) 490.651 → 491.000 Since 6 > 5 (vi) 2492.201 → 2492.000 Since 2 < 5 (vii) 67.737 → 68.000 Since 7 > 5 (viii) 423.27 → 423.00 Since 2 < 5 (ix) 5381.09 → 5381.00 Since 0 < 5 (x) 420.93 → 421.00 Since 9 > 5 Related Links : ● Rounding Numbers.
