Answer 2

Step-by-step explanation:

(a)

730 round off to 700

998 round off to 1000

So, Estimated sum = 700 + 1000 = 1700

(b)

796 round off to 800

314 round off to 300

So, Estimated sum = 800 - 300 = 500

(c)

12904 round off to 13000

2888 round off to 3000

So, Estimated sum = 13000 + 3000 = 16000

(d)

28292 round off to 28000

21496 round off to 21000

So, Estimated difference= 28000 - 21000 = 7000
