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
Two such numbers:
1 2/5 + 1 1/3
To nearest whole number: 1 + 1 = 2
To nearest half: 1½ + 1½ = 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.
750.4 if rounding to the nearest whole number. 754, if rounding to the nearest 10. 774, if rounding to the nearest 50. 874, if rounding to the nearest 250.
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
900
Rounding both numbers to the nearest ten it is about 80

They both involve rounding numbers.
400 + 500 = 900
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.
You use rounding TO estimate. For instance, estimating is 2.8 + 3.9 is about 7. Rounding is 2.8 is about 3 and 3.9 is about 4. When you estimate, you're rounding MULTIPLE numbers which you will then add, multiply, etc. to get an ESTIMATE! when you're rounding, you need to be given a certain number and you make it less specific. for example, the population of whoville is 693044. if I'm rounding to the nearest thousand, then the answer is 693000. numbers 5 and up are rounded up. numbers 4 and below are rounded down. when you're estimating, you're basically making an educated guess without knowing the real number. for example, you're looking at a bag of jellybeans and you guess there's 750 in there. it seems like a reasonable number so you estimate that.
