Question

Estimate each of the following using general rule :35,376-31,832​

Answer 1

Answer:

730 + 998

Rounding off 730 to the nearest hundreds we get, 700

And rounding off 998 to the nearest hundreds we get, 1,000

Therefore, 700 + 1000 = 1,700

Therefore, estimate of 730+998 is equal to 1,700 according to the general rule.

Step-by-step explanation:

796 – 314

Rounding off 796 to the nearest hundreds we get, 800

And rounding off 314 to the nearest hundreds we get, 300

Therefore, 800 - 300 = 500

Therefore, estimate of 796 – 314 is equal to 500 according to the general rule.
