two and one over eight

two and one over two

3

2

Answer 1

\[\left(3 + \frac{7}{8}\right) - \left(1 + \frac{3}{4}\right)\]

Answer 2

This is what you have to begin with

Answer 3

kk

Answer 4

aha

Answer 5

Keep in mind that you can distribute the negative and remove the parentheses:

\[3 + \dfrac{7}{8} - 1 -\dfrac{3}{4}\]

Answer 6

yep

Answer 7

Afterwards you can pair the whole numbers together and the fractions together

Answer 8

okay

Answer 9

\[3 - 1 + \dfrac{7}{8} - \dfrac{3}{4}\]

Answer 10

You know what 3 - 1 is

Answer 11

ok

Answer 12

yes

Answer 13

3 - 1 = 2 so

you have

\[2 + \dfrac{7}{8} - \dfrac{3}{4}\]

Answer 14

yess

Answer 15

:)

Answer 16

Now try to figure out what \(\dfrac{7}{8} - \dfrac{3}{4}\) equals

Answer 17

8-4=4
7-3=4 4/4 = 1 whole

Answer 18

We don't subtract fractions like that

Answer 19

okay

Answer 20

We can only subtract fractions properly if they have the same denominator

Answer 21

so i simplify

Answer 22

You have to learn how to subtract fractions first before attempting this problem.

Answer 23

hello @WHAT?!

Answer 24

31/8 − 7/4

Answer 25

YES THAT IS WHAT I DID

Answer 26

ok

Answer 27

31/8 − 7/4

= ((31 × 4) − (7 × 8)) / (8 × 4)

= (124 - 56) / 32

= 68/32

= 17/8

= 2 1/8

Answer 28

okay

Answer 29

@carolinagb02, you know how to do that but you don't know how to do \(\dfrac{7}{8} - \dfrac{3}{4}\)

Answer 30

@WHAT?!

Answer 31

ARE YOU THERE?

Answer 32

7/8 − 3/4

= ((7 × 4) − (3 × 8)) / (8 × 4)

= (28 - 24) / 32

= 4/32

= 1/8

Answer 33

@Hero , please don't do that

Answer 34

just \[\frac{Log4}{Log8}\]

Answer 35

can you help?

Answer 36

@angel12310 what does that mean?

Answer 37

what does what mean?

Answer 38

what does the list mean?

Answer 39

Answer 43

Answer 44

@carolinagb02, you think you need to be 22 in order to understand how to do

\[\dfrac{7}{8} - \dfrac{3}{4}\]

Answer 45

7/8 − 3/4

= ((7 × 4) − (3 × 8)) / (8 × 4)

= (28 - 24) / 32

= 4/32

= 1/8

Answer 46

No, she thinks you have to be 22 to do\[\frac{ \log4 }{ \log8 }\]

Answer 47

thats wierd

Answer 48

0.66666666666

Answer 49

@carolinagb02 anymore questions??

Answer 50

@angel12310

\[\frac{7}{8} - \frac{3}{4} \\= \frac{7}{8} - \frac{3}{4} \times \dfrac{2}{2} \\=\frac{7}{8} - \frac{6}{8}\\=\frac{1}{8}\]

Answer 51

I just wanted 1 answer!

Answer 52

but I get a bunch of tests ;( and I came here for 1 simple answer

Answer 53

Well, take Hero's word for it. I'm sure he's far more educated than all of us.

Answer 54

Of course there's only one answer, but you have to understand how to get that answer.

Answer 55

Subtracting the fraction is only part of the solution.

Answer 56

Besides, OpenStudy isn't here to do your work for you, it's to show you how to do it so you can do it yourself later, when you can't ask other people for help. Like if you're taking a test or a quiz.

Answer 57

can someone give me that one answer I HAVE BEEN HERE FOR 33 MINUTES ON THE SAME QUESTION!!!!!!! it is frustrating

Answer 58

If we put all the steps together, we get:

\[\left(3 + \frac{7}{8}\right) - \left(1 + \frac{3}{4}\right)\]
\[3 - 1 + \dfrac{7}{8} - \dfrac{3}{4}\]
\[2 + \frac{1}{8}\]

Answer 59

@carolinagb02 you got stuck after I asked you to subtract the fractions.

Answer 60

I know but... YOU KNOW WHAT! WHATEVER I CANT FIND ONE DUMB QUESTION I QUIT OPENSTUDY AND IT IS ALL OF UR PPL'S FAULT!

Answer 61

Don't get frustrated. Just review how to add and subtract fractions and you'll be fine.

Answer 62

I JUST WANTED TO FIGURE SOMETHING OUT AND ALL I GOT WAS A TOTAL DISSAPOINTMENT!

Answer 63

I quit this job

Answer 64

@carolinagb02, it is impossible to master adding and subtracting mixed fractions until you have mastered adding and subtracting regular fractions.

Answer 65

someone PLEASE! give me and answer and stop criticizing me!

Answer 66

You cannot do this:

\[\left(3 + \frac{7}{8}\right) - \left(1 + \frac{3}{4}\right)\]

Before knowing how to do this:
\[\frac{7}{8} - \frac{3}{4}\]

Answer 67

and if u think ur not well you are! it is mean, unkind, disrespectful and annoying, P.S it shames the person!

Answer 68

you see! you just highlight peoples weaknesses!

Answer 69

@Hero this is why im not ur fan!

Answer 70

i gave the answer to you

Answer 71

31/8 − 7/4

= ((31 × 4) − (7 × 8)) / (8 × 4)

= (124 - 56) / 32

= 68/32

= 17/8

= 2 1/8

Answer 72

7/8 − 3/4

= ((7 × 4) − (3 × 8)) / (8 × 4)

= (28 - 24) / 32

= 4/32

= 1/8

Answer 73

@angel12310 , 2 1/8 can easily be confused with 21/8
It is not a good notation to use.

2 + 1/8 is the correct notation

Answer 74

what is a,b,c,and d

Answer 75

the 1st answer, the 2nd one the 3rd etc it goes by letter!

Answer 76

@carolinagb02, I know you are frustrated, but I cannot allow you to just simply ask for the answer. That's not how OS works

Answer 77

@Hero , how are you a moderator?

Answer 78

@carolinagb02, I understand that you are frustrated. Questioning my position as moderator really is not the issue.

Answer 79

he is smarter you should ask him if it's A.,B.,C.,or D.

Answer 80

I know, I just don't know if your a moderator because you have a 99 on ur status, I am not being rude, I just want to know how,

Answer 81
