The best estimate for the sum of 4523 and 1234 can be found by rounding each number to the nearest hundred. Rounding 4523 to the nearest hundred gives 4500, and rounding 1234 to the nearest hundred gives 1200. Adding these rounded numbers gives an estimated sum of 5700. This estimate provides a quick approximation of the actual sum while simplifying the calculation.
what is 34.76 rounded the nearest ten eqaul
The answer depends on whether the rounding is to the nearest hundreds, the nearest tens or nearest unit!

200 and 300, respectively.
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.

The best estimate for 83.74 plus 2.93 can be found by rounding each number to the nearest whole number. Rounding 83.74 to the nearest whole number gives us 84, and rounding 2.93 to the nearest whole number gives us 3. Adding these rounded numbers together gives us an estimate of 84 + 3 = 87.
