How to Estimate
Rounding Numbers
Decimals
When you estimate math problems, start by rounding off the numbers. Rounding makes math problems easier to estimate. If you're working with decimals, you might want to round to the nearest whole number. If you have a number with a decimal value of 0.5 or higher, you round up (5.7 rounds to 6, for instance). The opposite is also true - numbers with decimal values lower than 0.5 are rounded down. For instance, 4.3 rounds down to 4.



Try rounding to the nearest whole number as one technique.

Answer 12

okay but can you help me get the answer for the question

Answer 13

1.35 + 2.4 + 1.48 would be to the nearest whole number:

1 + 2 + 1 = 4

That is a rough estimate but an estimate nonetheless.

Answer 14

okay

Answer 15

can you help me get the answer anyone then i will medal you :D

Answer 16

I am looking for a second estimation technique.

I guess we could estimate to the nearest tenth as someone suggested.

Answer 17

okay

Answer 18

Rounding to the Nearest Tenth Estimation Technique

1.35 + 2.4 + 1.48 =

1.4 + 2.4 + 1.5 = 5.3 as the estimate

Answer 19

@lauren.ascough

I need an heroine.

Would you find the exact sum of 1.35 + 2.4 + 1.48 and post what you get?

Answer 20

Need that sum to get a wrap @lauren.ascough

Answer 21

Enter this in the Google search box, and the Google calculator will barf up the sum.

"1.35 + 2.4 + 1.48 = "

Answer 22

Anybody viewing care to add these and produce a sum so that we can complete this thread?

@sweetburger @owen3

Answer 23

Am I even allowed to with the OS rules?

Answer 24

We are problem solving and this calculation is not the answer to the entire problem.

It is okay to give the answer to a part of a question. I would appreciate your doing so.

I have the other pieces ready to roll. I don't know why the OP will not respond.

Answer 25

>.Am I even allowed to with the OS rules? Yes.

Answer 26

yes

Answer 27

@lauren.ascough

Your task is to do this: Add these 3 numbers: 1.35 + 2.4 + 1.48 =

Answer 28

ok let me work that out

Answer 29

5.23?

Answer 30

is that right @Directrix

Answer 31

I did not get that.

Copy and paste this in the Google search box, and the Google calculator will barf up the sum. "1.35 + 2.4 + 1.48 = "

Answer 32

If you crank this out by hand, be sure to get the decimals in alignment.

1.35
2.40
1.48
------

Answer 33

is it 5. something

Answer 34

>>5.23?

I am now thinking that I messed up and this is the sum.

I apologize for saying that it is not correct. I did get something different but messed up myself.

Answer 35

Comparison Chart
----------------

Whole Number Technique --> 4
Nearest Tenth Technique --> 5.3
Actual Sum --> 5.23

Answer 36

That leaves this question to be answered:

How do these compare to the actual solution? @lauren.ascough

Answer 37

Rules to round off numbers.

1. If the number to be round off is greater than 5 then the previous digit will increase by 1. Example :- 4.46=4.5

2.If the number to be round off is less than 5, then previous digit will remain as it is.
Example- 4.44=4.4

3.If number to be round off is 5. two cases arise

(i) when previous digit is even, we will drop 5 without making any change to previous digit.
(ii)when previous digit is odd, we will increase previous digit by 1 .

Answer 38

umm idk

Answer 39

Nearest tenth technique appears to be more accurate than the nearest whole number technique.

Answer 40

okay

Answer 41

>>3.If number to be round off is 5. two cases arise

I have seen that rounding rule for the .5 case but the rule is not an absolute.

Answer 42

ok so can you send me what i would write for the question
