Question

I am having a hard time with this question. I've ran through it several times and my answer check never pans out. Any help would be appreciated! Thanks!

2 p+1
--- + --- = 5
5p p

Answer 1

what do you need in order to add fractions together?

Answer 2

A common denominator.

Answer 3

exactly so what will our common denom be?

Answer 4

Is it 5p?

Answer 5

yes

Answer 6

Thanks for your help! I'm going to give this a run

Answer 7

let me know if you get stuck!

Answer 8

@mramirez686 Pay attention to the right side:
5 is 5/1

Answer 9

I'm still running into a wall here. Anyone have an example to show me by chance?

Answer 10

Show us what you got?

Answer 11

@mramirez686 How do you get common denominator?

Answer 12

\[\frac{ 2 }{ 5p } + \frac{ p+1 }{ p } = \frac{ 5 }{ 1 }\]Is what I have, so far given the input provided from everyone. Knowing that the common denominator I am going for is 5p. But I am doing so to cancle the fractions? I feel like I've been running around in circles with this and the examples in the book seem almost unrelated.

Answer 13

so how do we get the common denominator?

Answer 14

factorizing and finding what is common between them?

Answer 15

You already had the first denominator is 5p, now what do you multiply with the second fraction to get 5p?

Answer 16

Hint: look at the second denominator!

Answer 17

right, you would multiply 5 to get 5p

Answer 18

Great, at least some move here!
So what the second fraction becomes after multiply by 5?

Answer 19

5p+5/5p

Answer 20

excellent!
Now what should you multiply to with the right side to get the denom. 5p?

Answer 21

* multiply to the right side

Answer 22

1/5p?

Answer 23

What fraction on the right side?

Answer 24

before you multiply?

Answer 25

well, assuming 5 is the same as 5/1?

Answer 26

Right, now multiply 5/ 1 with ...?

Answer 27

5p, so = 25p on the right

Answer 28

5 * 5P / 1 * 5P = ...?

Answer 29

25p/5p

Answer 30

Now, look back to make sure all the fractions have the common denom?
If so, it's safely to add ....?

Answer 31

yes, 5p+7/5p = 25p/5p

Answer 32

would I multiply by 5p to cancel out the fractions? or am I missing a step here

Answer 33

NO, the goal is COMMON DENOMINATOR = 5P!

Answer 34

After you have common denom. 5p, cross out the denom! What left is numerator :)

Answer 35

Is the question solving for p?

Answer 36

I'm assuming, it says solve and verify.

Answer 37

So what's in the numerators now?

Answer 38

5p +7 = 25p

Answer 39

Can you solve for p now?

Answer 40

either way I do it, I am getting a fraction that isn't checking out when plugged back in

Answer 41

7/20 = p

Answer 42

Oh, so it does check out. Thank you so much! This has been an all day disaster for me :/

Answer 43

i've ran through this problem probably a hundred different wrong ways. Knowing that the common denominator cancels out helps out a lot. Makes more sense.
