@texaschic101

Answer 4

@iGreen

Answer 5

please note that:
\[1 \frac{ 7 }{ 9 }=1+\frac{ 7 }{ 9 }=\frac{ 9+7 }{ 9 }=\frac{ 16 }{ 9 }\]

Answer 6

and:
\[6\frac{ 2 }{ 11 }=6+\frac{ 2 }{ 11 }=\frac{ 6*11+2 }{ 11 }=\frac{ 68 }{ 11 }\]

Answer 7

So what do you think that the first fraction will be rounded \(up\) to? What about the second fraction?

*hint* first one is rounded up, other is rounded down.

Answer 8

so you have to perform this subtraction:
\[\frac{ 16 }{ 9 }-\frac{ 68 }{ 11 }=...\]

Answer 9

please, try!

Answer 10

o sorry i was doing somthin haha give me a sec :)

Answer 11

@Michele_Laino, in order to subtract these fractions, you need to have a LCD... :)

Answer 12

yes! you re right! @haleyelizabeth2017

Answer 13

But so it is easier, you just round the fractions first to the nearest integer and then you subtract. :) So that way we don't have to go through all of that fancy work :P

Answer 14

o.o im still confuised n i still have like 4 more left o.o n im on a time limit

Answer 15

Okay. So we will round them first. The first one goes up to what??

Answer 16

Okay, I think I might just show you on this one..... so the first one rounds up to 2, and the second one rounds down to 6. 2-6=-4....do you understand now?

Answer 17

ya kinda i got a idea of it now

Answer 18

:) ima see if i ca do the next one :) ill post another question if i cant or dont understand it :)

Answer 19

Okay :)

Answer 20

o.o Estimate by first rounding each number to the nearest 1/2 .

A.

–6


B.

–3


C.

6


D.

8

Answer 21

A n B r negative

Answer 22

the first one can be rounded up to -4, and the second one can stay the same...just type in -4 * 1.5 into a calculator and that will be your answer. Or you can do 1*-4 and then .5*-4 then add them together.

-4*1=-4
.5*-4=-2

So the answer is -6

Answer 23

ooooo okk

Answer 24

yup yup

Answer 25

xd i have another but just so u know im not just looking for an answer for them xd this one is different from the others..

Joseph wants to estimate 1 3/7 times 5 4/5 . To estimate, he simplifies the expression 1 1/2 times 6 .



Is Joseph’s estimate a close estimate, an underestimate, or an overestimate?





A.


underestimate


B.


overestimate


C.


close estimate

Answer 26

lol Joseph's

Answer 27

I'm not sure....sorry! I'm not good at these types :(

Answer 28

o men :( its ok i guess

Answer 29

I really am sorry!

Answer 35

ok :)

Answer 36

Answer 37

@Destinymasha

Answer 38

\(1\dfrac{7}{9} + 6 \dfrac{2}{11} \)
The instructions are to estimate the sum by rounding each mixed numeral to the nearest integer.
In a fraction, if the numerator is exactly half of the denominator, the fraction is equal to 1/2. 1/2 is an example of this, of course, since 1 is half of 2. 3/6 is the same as 1/2 since 3 is half of 6. 5/10, 12/24, 13/26 are all equal to 1/2 since in each case the numerator is half the deominator.

Answer 39

In your case, the first mixed numeral includes the fraction 7/9.
Since 7 is more than half of 9, 7/9 is more than 1/2, so \(1 \dfrac{7}{9}\) rounded to the nearest integer is 2, because \(1 \dfrac{7}{9} \) is more than \(1 \dfrac{1}{2} \).

Answer 40

erm.....@mathstudent55 quick edit of your thoughts......1 3/7 times 5 4/5 is what they are....

Answer 41

With your other mixed numeral, you have the fraction 2/11.
Since 2 is less than half of 11, 2/11 is less than 1/2, so \(6 \dfrac{2}{11}\) rounded to the nearest integer is 6, because \(6 \dfrac{2}{11} \) is less than \(6 \dfrac{1}{2} \).
Then the estimate of the sum is 2 + 6 = 8

Answer 42

Sorry, above I did the wrong operation.
They ask for a subtraction, so using the estimates, 6 - 2 = 4.
The answer is 4.

Answer 43

Oh you did the first one :P whoopsies! my bad

Answer 44

@haleyelizabeth2017
1) A post is supposed to be for one question only. Writing a number of questions on a post just makes it too long and confusing.
2) I can help you with the newest question, but the original question was never dealt with correctly, so I decided to start from the beginning.

Answer 45

Sorry. This is the one she needs help with :)

Joseph wants to estimate 1 3/7 times 5 4/5 . To estimate, he simplifies the expression 1 1/2 times 6 .
Is Joseph’s estimate a close estimate, an underestimate, or an overestimate?

A. underestimate

B. overestimate

C. close estimate

Answer 46

yep

Answer 47

@Michele_Laino's answer does not deal with the estimation that the problem asks for. It's simply a subtraction of fractions.

Answer 48

Sorry. but wouldn't it be 2-6 since it was 1 7/9 - 6 2/11? You would leave it in the same order as originally asked.

Answer 49

Yes, you are correct. It is 2 - 6 = -4
I won't answer this post any more.
Every time I need to see a question I need to scroll up and down.
Keep posts to one single question. Start a new post for every new question. Then I'll try rto help.

Answer 50

Okay so @Kayla369 can you copy this:

Joseph wants to estimate 1 3/7 times 5 4/5 . To estimate, he simplifies the expression 1 1/2 times 6 .
Is Joseph���������������������������s estimate a close estimate, an underestimate, or an overestimate?

A. underestimate

B. overestimate

C. close estimate

And paste it into a new question so it is easier?

Answer 51

Also, if you need to include a simple operation in a post, draw it or use the equation editor. Having to constantly go to links for a simple subtraction of mixed numerals is too much work.

Answer 52

ok

Answer 53

brb guys

Answer 54

Ok, I'll finish this last question.

Answer 55

Notice which numbers he is using for the estimate.
He is using 1 1/2 instead of 1 3/7.
Is 1 1/2 greater than or less than 1 1/2?

Answer 56

Then look at the second number he is using.
He is using 6 instead of 5 4/5.
Is 6 greater than or less than 5 4/5?

Answer 57

i put it into a new question n taged u @mathstudent55

Answer 58

Ok, thanks. I'll go there.
