(3) Estimate the following product using general rule
(a.) 578 * 161
General Estimation Rule:
Round off each number to its greatest place
So we have to multiply 600 * 200 = 1,20,000
Hence 1,20,000 is our answer
b. 5281 * 3491
So now we got==> 5000 * 3000 ==> 1,50,00,000
c. 1291 * 592
Hence, according to general approximation we get
1000 * 600 ===> 6,00,000
d. 9250 * 29
Hence 9000 * 30 ==> 2,70,000
