Answer:
Estimation is the process of estimatimg the answer of any question without solving the actual values so as to get the nearer value.
Explanation:
Estimation : It is the process of solving the question by estimating the value of both numbers following by the operation asked in it.
General rule of estimation:
It states that the rounding of the number to its greatest place.
Rounding off has rule that if a number rounded is followed by a number which is 5 or greater than 5 then the number is increased up and if the number to be rounded is followed by a number which is less than 5 the. number is left like that only and it is decreased down.
55662 = 60000
3465 = 3000
60000 - 3000 = 57000
27348 = 27000
68999 = 70000
27000 + 70000= 97000
4578 = 4600
123982 = 100000
100000 × 4600
= 460000000
Sometimes, Estimation gives us a more. realistic and accurate answer by consuming less time. It is an easier process to solve any complex question.
