Answer: a)The first step in estimating a sum or a difference is to round the numbers, by changing them to the nearest power of ten, hundred, thousand, etc. Round the numbers first, then use mental math to estimate an answer. When rounding, follow these rounding rules: If the number being rounded is less than 5, round down.
b)Estimate the product to the nearest hundreds. 2. Find the estimated quotient 2838 ÷ 125 by rounding off the numerator and denominator to the nearest hundreds. Therefore, estimated quotient = 2800 ÷ 100 = 28.
