Answer

(a) 253 (b) 135

Work Step by Step

To round 252.662 and 134.8 to the nearest whole numbers, draw a "cut-off" line after the ones place for each: "252" and "134". Next, look at the first number after the cut-off line: "6" and "8". If the number is 5 or above, round up to the nearest whole number: "253" and "135". Note: You are rounding to the nearest whole number, so do not show any decimal places.
