  • 1 answers

Yogita Ingle 5 years, 2 months ago

(a) 730 + 998 = 700 + 1000 = 1700

(b) 578 x 161

Rounding off 578 to the nearest hundreds, we get 600

And, rounding off 161 to the nearest hundreds, we get 200

Therefore, 600 x 200 = 1,20,000

It means that estimate of 578 x 161 is equal to 1,20,000 according to the general rule.
