A store sold 1,458 toys in January, 1,642 toys in February, and 1,289 toys in March.

  1. Round the total number of toys sold in each month to the nearest hundred.
  2. Determine which month had the greatest number of toys sold after rounding.


  • January: 1,458 rounds to 1,500 (because 58 is closer to 100).
  • February: 1,642 rounds to 1,600 (because 42 is closer to 0).
  • March: 1,289 rounds to 1,300 (because 89 is closer to 100).

  • Determine which month had the greatest number of toys sold after rounding:

    • January: 1,500
    • February: 1,600
    • March: 1,300
    • Greatest: February had the greatest number of toys sold after rounding.
