Question

PLZ HELP 20 PTS

Use rounding to determine if the answer is reasonable. Round each of the factors to the nearest ten, then multiply. 117 × 19 = 222.3

Answer 1

117 * 19

= 120 * 20 to the nearest 10

= 2400 which indicates that 2223 is a reasonable answer.

Answer 2

Its not correct because the answer would be 1,440 (rounded) this is no where near as close as 222.3.
