Why is rounding closer to the actual weight than compatible with these numbers 9.4 and 62.6?

Rounding is closer because the amount added to one number is the same as the amount subtracted from the other number which makes the answer match exactly.

When you use compatible numbers to estimate 9.4 plus 62.6 is it closer to the actual answer then using rounding?
Not in this case.
What is 6541 closer to rounding to the nearest thousand?
7,000
Is 942 rounded closer to 940?
Yes, when rounding to the nearest 10.
What is 8834 rounding to the neraest thousand?
10000 because 8 is closer to 10 than 5 or 0
When you are estimating sums and differences of fractions by rounding how do you know to round it to zero half or one?
Let's say that you are rounding 2/5. You find half of 5 which is 2.5. Then you see if 2 is closer to 0, 2.5/5, or 1. It is closer to 2.5, so you would say that 2.5 is half of five, so your answer is 1/2. If you are doing 1/7, 1 is obviously closer to 0, so your answer would be 0.
When you use compatible numbers to estimate 9.4 plus 62.6 is it closer to the actual answer then using rounding?
Not in this case.
What is the purpose of rounding numbers?
the purpose of rounding numbers is that you can get closer to the actual answer
Explain whether it is easier to estimate the product 13.72 x 47.28 by using compatible numbers or by rounding each factor to the nearest whole number?
Compatible numbers would be easier. Rounding gives you 14 x 47. Compatible numbers could be 13 x 50 which would be closer to the actual product.
Estimate the total weight of two boxes that weight 9.4 lb and 62.6 lb using rounding and compatible numbers which estimate is closer to the actual total weight why?
rounding:9lb+63lb=about 72lb
Estimate the total weight of two boxes that weigh 9.4 lb and 62.6 lb using rounding and compatible numbers Which estimate is closer to the actual total weight Why?
9+63+863+9
Are rounding and compatible numbers the same thing?
Not necessarily. Take this example: 89 ÷ 44 The rounding rules are clear. 89 goes to 90, 44 goes to 40, 90 ÷ 40 = 2.25 Compatible numbers can be altered by the relationships between them. 89 is close to 90, 44 is close to 45, 90 and 45 have a relationship that is easy to compute. 90 ÷ 45 = 2 In this case, the estimate provided by compatible numbers is closer to the real total than the one provided by rounding.
What is a compatible fraction?
What are compatible fractions? Round the whole number to the closest compatible number to the denominator. Compatible numbers are numbers that are close in value to the real number that would make it easier to find an estimate calculation. compatible numbers are numbers that are a like or can compared like fact families! Compatible numbers When estimating, compatible numbers are numbers that are close in value to the actual numbers, and which make it easy to do mental arithmetic. In mathematics, compatible numbers are the numbers that are easy to add, subtract, multiply, or divide mentally. Compatible numbers are close in value to the actual numbers that make estimating the answer and computing problems easier. We can round the numbers to the nearest ten, hundred, thousand or ten thousand to make them compatible numbers. For instance, if we have to add 493 and 549, we can make the numbers compatible by rounding them up to the nearest tens or hundreds. 490 and 550 (rounded to the nearest tens) or 500 and 500 (rounded to the nearest hundreds) are much easier to solve. So, we know the answer is about 1040 or 1000. Let us see some examples to understand how we can perform subtraction, multiplication and division using compatible numbers. Subtraction: Find the difference between 376.5 and 612.2 Here, we cannot find the difference between 376.5 and 612.2 easily as they are not compatible. So, we make the numbers compatible by rounding both the numbers to the nearest tens. Multiplication: Find the product of 24.3 and 18.7. It is difficult to find the product of 24.3 and 18.7 mentally and quickly. So, we use compatible numbers and find the which is closer to the actual answer. Division: Divide 856 by 33. To find the answer to 856 ÷ 33, will take us time as we need to divide to get the answer. However, if we make the numbers compatible, we can mentally find an answer close to the actual answer as shown. Fun Facts Compatible numbers help in simplifying the calculation of an estimate only.
Is 39.948 closer to 39 or 40?
Depends if you are rounding up or rounding down to nearest whole number.
What is 6541 closer to rounding to the nearest thousand?
7,000
Is 942 rounded closer to 940?
Yes, when rounding to the nearest 10.
How do you round the number 94 with compatible numbers?
You can round it to the nearest 10: Its closer to 90 than it is to 100, so 90 is the answer. Or you can round it to the nearest 100, its closer to 100 than 0, so 100 is the answer
What is a definition of rounding numbers?
It means that you find the closest whole number. For example, if you have the number 5.8, rounding it to a whole number gives you 6 - since no other whole number is closer to 5.8.More generally, it can mean rounding to some multiple of a certain number. For example, 549 rounded to the nearest 100 (i.e., to the nearest multiple of 100) gives you 500 - since no other multiple of 100 is closer to 549.
