Hi

OpenStudy (anonymous):

hey

OpenStudy (anonymous):

@waterfall500 i hate to ask but could you maybe take a look at these... i totally understand if you say no

OpenStudy (anonymous):

How can I help you today?

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

i would be happy too! :)

OpenStudy (anonymous):

what would be your questions?

OpenStudy (anonymous):

they are in the screen shot i posted i just need help with trying to figure out these types of problems for my calc test tomorrow

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

Let us do second problem okay?

OpenStudy (anonymous):

add the 2 numbers together...

OpenStudy (anonymous):

25

OpenStudy (anonymous):

and thats the denominator Correct?

OpenStudy (anonymous):

correct

OpenStudy (anonymous):

so how many rulers have no labels?

OpenStudy (anonymous):

10

OpenStudy (anonymous):

so c?

OpenStudy (anonymous):

yep, and 15 do right?

OpenStudy (anonymous):

so, since you added those numbers together, that's how many rulers are there in all-25

OpenStudy (anonymous):

so is there any number that can go into 10 and 15 that you can think of?

OpenStudy (anonymous):

the highest number that can go into both 10 and 15

OpenStudy (anonymous):

5

OpenStudy (anonymous):

how many times does 5 go into 10?

OpenStudy (anonymous):

2

OpenStudy (anonymous):

yep, so 2 is your top number

OpenStudy (anonymous):

and your bottom number is always the number you added the 15 and 10 into

OpenStudy (anonymous):

so you added 25, so how many times does 5, go into 25?

OpenStudy (anonymous):

2/5 ?

OpenStudy (anonymous):

sorry 5

OpenStudy (anonymous):

5, right?

OpenStudy (anonymous):

so your answer would be 2/5

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

so you practacly just have to take 10+15=25, then 10 divided by 5, then 25 divided by 5.

OpenStudy (anonymous):

okay and do the same steps for the next two?

OpenStudy (anonymous):

do you get it now? it's ok if you don't, i can explain in a better way lol

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

do you want to do them together, to make sure you understand, or i could check your answers if you want me to

OpenStudy (anonymous):

that would be great

OpenStudy (anonymous):

ok, do you want to do them together, or for me to check them?

OpenStudy (anonymous):

is 26. c?

OpenStudy (anonymous):

yep, you are correct lol

OpenStudy (anonymous):

27. a?

OpenStudy (anonymous):

27 should be 1/4, that's weird lol, 1 sec. let me look at this closer lol

OpenStudy (anonymous):

i think it is a because it is only out of the large marbles right?

OpenStudy (anonymous):

yea, your right

OpenStudy (anonymous):

and what grade are you in? I'm just wondering lol

OpenStudy (anonymous):

junior

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

why?

OpenStudy (anonymous):

cause i learned this stuff when i was in 6th grade lol

OpenStudy (anonymous):

and i still remember it lol

OpenStudy (anonymous):

i know its supposed to be like a basic math review because we finished all of our calculus and took the ap exam last week but for some reason I couldn't remember

OpenStudy (anonymous):

oh, ok, that's understandable, I'm in the same grade as you so yea, that's kind of cool lol

OpenStudy (anonymous):

well, i better get going now, see ya! :)

OpenStudy (anonymous):
