Question

Estimation Estimate each sum or difference

25 5/18 - 9 11/17

Answer 1

Well, do we need to solve this and then estimate or are these two different numbers and we just need to estimate the two different numbers? Ok, to estimate these two numbers we can take the fraction and then turn it into a decimal. For instance:

25 5/18
5/18 = .277
25 + .277 = 25.277
25.277 = 25 if we are estimating to the nearest ones.
25.277 = 25.20 if we are estimating to the nearest tenths
25.277 = 25.28 if we are estimating to the nearest hundredths

Can you do the next one?

Answer 2

i dont really understand

Answer 3

Does your direction tell you what to estimate to? Are you to just estimate to the nearest ones?

Answer 4

Do you know how to take a fraction and turn it into a decimal?

Answer 5

it just say estimate each sum or difference

Answer 6

Ok, does it give you answers to chose from?

Answer 7

no

Answer 8

For -9 11/17

-9 11/17
11/17 = .647
-9 + .647 = -9.647
-9.647 = -10 if we are estimating to the nearest ones.
-9.647 = -9.60 if we are estimating to the nearest tenths
-9.647 = -9.65 if we are estimating to the nearest hundredths

You pretty much are turning the fraction into a decimal and then rounding to what ever place they want you to round / estimate to. I am assuming the ones place so your answer would be

25 and -10 for the two numbers

Answer 9

how do i get answer

Answer 10

You need to take the fraction and turn it into a deciaml. Once you have the decimal you need to round the number. Do you know how to round numbers and turn a fraction into decimals?
