1 and 1/3 + 1 and 1/3.
Rounded to the nearest whole and added together: give 1 + 1 = 2
Rounded to the nearest half and added together: give 1.5 + 1.5 = 3
rounding numbers is to nearest ten or hundred and compatible numbers are when you can do nearest 5
In whole numbers, rounding to the nearest ten is better. And in decimals, rounding to the nearest hundreth is more accurate.
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.
400 + 500 = 900
Infinitely many, since between any two numbers, there are always additional numbers. The exact range of numbers that can be rounded to 3000 depend on how you are rounding - specifically, if you are rounding to the nearest integer, the nearest 10, the nearest 100, or the nearest 1000.
Rounding both numbers to the nearest ten it is about 80

They both involve rounding numbers.
400 + 500 = 900
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.
It depends on the degree of rounding required. To the nearest whole numbers or nearest thousands, for example, they would remain unchanged.It depends on the degree of rounding required.

The answer will depend on the degree of rounding. To the nearest ten, it is 39120 To the nearest million, it is 0.
