63.15 x 87.64 can be estimated as 63 x 88, or 5544. The actual product is 5534.466

∙ 8y agoYou round each multiplicand to the nearest whole number and then multiply the two whole numbers.
For example, 2.4 * 9.9 would be estimated by 2*10 = 20

So take 467 now round that and think Will this round to 400 or 500 if you are smart enough you would get 500 because it is over 450

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 Estimate 59.25 by rounding each value to the nearest whole number?

Does rounding up mean the same thing as estimate?
An estimate is an educated guess based on prior knowledge. Rounding off is knowing the exact value but rounding it to the nearest whole number.
How do you round and estimate the number 813?
The answer will depend on the extent of rounding. To the nearest integer, it is 813. To the nearest million, it is 0.
What is the difference between estimate and rounding?
An Estimate is basically a guess. Rounding is when you have an answer and you shorten the answer to a given number of digits. eg $27482 would round to $27500 to the nearest hundred dollars.
Does rounding to the nearest whole number mean rounding to the nearest hundred?
No, it means rounding to the nearest whole number.The nearest whole number is the nearest one .The nearest whole number to 1.9 is 2 .So the nearest whole number to 1,624,381.9 is 1,624,382 .

How do you round 10π?
Depends on what you are rounding to. Rounding to the nearest whole number, it is 10. Rounding to the nearest tens, it is still 10. Rounding to the nearest hundred, it is zero.
