(a)796 – 314 (b) 12,904 +2,888
(c) 28,292-21, 496​

Answer 1

Answer:

(a) 500

(b) 16,000

(c) 10,000

Step-by-step explanation:

(a) 796 - 314

   = 796 to the nearest hundreds = 800

   = 314 to the nearest hundreds = 300

   = 800 - 300

   = 500 (answer)

(b) 12,904 + 2,888

    = 12,904 to the nearest thousands = 13,000

    = 2,888 to the nearest thousands = 3000

    = 13,000 + 3000

    = 16,000 (answer)

(c) 28,292 - 21,496

    = 28,292 to the nearest ten thousands = 30,000

    = 21,496 to the nearest ten thousands = 20,000

    = 30,000 - 20,000

    = 10,000 (answer)
