8 5/8 - 2 2/3 =?

OpenStudy (anonymous):

Well first convert the improper fractions to a proper fraction, so \[\frac{ 69 }{ 8 } + \frac{ 8 }{ 3 }\]

OpenStudy (anonymous):

oh wait, minus, sorry

OpenStudy (anonymous):

Then you're gonna wanna find the LCM for 8 and 3, which is 24 (8x3)

OpenStudy (anonymous):

Then multiply the left fraction with 3 up and down, and the right one with 8 up and down. You'll get \[\frac{ 207 }{ 24 } - \frac{ 64 }{ 24 } \]

OpenStudy (anonymous):

Then subtract the numerators as you would normally, and simplify. If need be, then convert it back into an improper fraction, depending on what the question is asking for. So you'd get \[\frac{ 143 }{ 24 }\]

Makes sense momo?

OpenStudy (momo_loves_cte):

not really but im not to smart

OpenStudy (momo_loves_cte):

that isnt one of my answer options either

OpenStudy (anonymous):

can you retype the question in the equation format so that I can see the question properly? It's not too clear above.

OpenStudy (momo_loves_cte):

5 7/24 5 23/24 6 3/5 these are my answer options

OpenStudy (anonymous):

Yeah, so you'd have to convert it back into the improper format

OpenStudy (momo_loves_cte):

i am confused

OpenStudy (anonymous):

It would be the second option

OpenStudy (anonymous):

What's confusing you?

OpenStudy (momo_loves_cte):

math

OpenStudy (momo_loves_cte):

this question

OpenStudy (anonymous):

Come on man, what are you finding hard? Maybe I can explain it again, or in a different way.

OpenStudy (momo_loves_cte):

im just confused about what the answer is

OpenStudy (anonymous):

the answer is the middle one, the 5 23/24, which is the same thing as the one that I showed you. Would you like me to explain the conversion between proper and improper fractions?

OpenStudy (momo_loves_cte):

thank you!!! will you help me with the next one?

OpenStudy (anonymous):

Sure, will do.

OpenStudy (anonymous):

Why don't you post that as a separate question?

OpenStudy (momo_loves_cte):

okay
