5. Estimate each of the following by mounding of each number nearest to it

place
(1)730 + 998(2) 5,290 + 17,986
(4)28, 292 - 21 ,496 ( 3)796-314

​

Answer 1

Step-by-step explanation:

1)1728

2)23275

3)482

4)6796

Answer 2

(1) 730+998

Rounding of to nearest hundred

730 = 700 and 998 = 1,000

730+998 = 700+1,000

= 1,700

(2) 5,290+17,986

Rounding of to nearest thousand

5,290 = 5,000 and 17,986 = 18,000

5,290+17,986 = 5,000+18,000

= 23,000

(3) 796-314

Rounding of to nearest hundred

796 = 800 and 314 = 300

796-314 = 800-300

= 500

(4) 28,292-21,496

Rounding off to nearest thousand

28,292 = 28,000 and 21,496 = 21,000

28,292-21,496 = 28,000-21,000

= 7,000
