Round 498.32 to nearest 100:
498.32 ~= 500
Round 10.53 to nearest 10:
10.53 ~= 10
So 498.53 x 10.53 ~= 500 x 10
= 5000

Estimate 5.12 plus 4.35 by first rounding to the nearest whole number?
It is 5 + 4 = 9.
What is front end rounding of 75?
Front end rounding is taking the first digit and making the rest 0. 75 would be 70 in front end rounding.
What is front end rounding of 37145?
Front end rounding is using the first or the first two digits to make an estimation. 37145 would be rounded to 40000.
What Estimate the answer to 398.22 93.87 by first rounding each number to the nearest one?
398.22 * 93.87 = 398 * 94 = (400 - 2)*(90 + 4) = 36000 + 1600 - 180 - 8 = 37,412 The exact answer, using a calculator, is 37380.9114. So the estimate is too large by 0.08%

Estimate 5.12 plus 4.35 by first rounding to the nearest whole number?
It is 5 + 4 = 9.
Estimate and acirc and 136 and 1462633211987 by first rounding each number to the nearest thousand.?
There is only one number, 2633211987 in the question so why estimate?
What does estimate the sum by first rounding to the nearest whole number?
A mathematician in a hurry or one who is only interested in an approximate answer does it.
Estimate 5.12 plus 4.35 by first rounding to the nearest whole number.?
The estimated answer is 20.
Rounding off to the first digit is called?
Rounding to the first digit is simply called rounding. This will make the number equal to the same as what the number truly is.
Estimate the sum or difference by rounding first 3 67 4 1112?
8/11 + 3/9 8/11 + 3/9
What is front rounding of numbers?
The name comes from the way you round. Front end rounding is keeping the first number and rounding all the numbers after that.
What is front end rounding of 75?
Front end rounding is taking the first digit and making the rest 0. 75 would be 70 in front end rounding.
What is front end rounding of 37145?
Front end rounding is using the first or the first two digits to make an estimation. 37145 would be rounded to 40000.
What are the rules to Estimating products and quotients of mixed numbers?
Estimating sumsUse rounded numbers to estimate sums.Example 1Give an estimate for the sum of 19.61 and 5.07 by rounding to the nearest tenth.Round each number to the nearest tenth.Example 2Estimate the sum of 19.61 + 5.07 by rounding to the nearest whole number.Round each number to a whole number.Estimating differencesUse rounded numbers to estimate differences.Example 3Give an estimate for the difference of 12.356 - 5.281 by rounding to the nearest whole number.Round each number to the nearest whole number.Now subtract.So 12.356 - 5.281 ≈ 7.Estimating productsUse rounded numbers to estimate products.Example 4Estimate the product of 4.7 × 5.9 by rounding to the nearest whole number.Round each number to a whole number.So 4.7 × 5.9 ≈ 30.Again, in decimals, as in whole numbers, if both multipliers end in .5, or are halfway numbers, rounding one number up and one number down will give you a better estimate of the product.Example 5Estimate the product of 7.5 × 8.5 by rounding to the nearest whole number.You can also round the first number down and the second number up and get this estimate.In either case, your approximation will be closer than it would be if you rounded both numbers up, which is the standard rule.Estimating quotientsUse rounded numbers to estimate quotients.Example 6Estimate the quotient of 27.49 ÷ 3.12 by rounding to the nearest whole number.Round each number to the nearest whole number.
What is the estimate of the product 79 and 13?
The idea is to round both numbers to the nearest multiple of 10 (in this case), then multiply. After rounding, you should be able to do the multiplication in your head - but if you have trouble with that, try to do it with pencil and paper first.
