p-1/4 times 3= -5/6

OpenStudy (x3_drummerchick):

\[p-\frac{ 1 }{ 4 } * 3 = \frac{ 5 }{ 6 }\] is this correct?

OpenStudy (anonymous):

yes but the 5/6 is negative, I just double checked

OpenStudy (x3_drummerchick):

or is it \[(p-\frac{ 1 }{ 4 }) *3 = -\frac{ 5 }{ 6 }\]

OpenStudy (anonymous):

It is the first way you typed it out. Only -5/6

OpenStudy (x3_drummerchick):

okay

OpenStudy (x3_drummerchick):

once again, lets play with the order of operations: P arentheses E xponents M ultiplication D ivision A ddition S ubtraction multiply (-1/4) * 3 first

OpenStudy (x3_drummerchick):

then you should get \[p - \frac{ 3 }{ 4 } = - \frac{ 5 }{ 6 }\]

OpenStudy (anonymous):

Yes, we got 3/4

OpenStudy (x3_drummerchick):

negative 3/4, dont forget the negative sign attatched to it

OpenStudy (anonymous):

yes

OpenStudy (x3_drummerchick):

now you can solve for p. use the inverse operation to add 3/4 to both sides. \[p = \frac{ 3 }{ 4 } - \frac{ 5 }{ 6 }\]

OpenStudy (x3_drummerchick):

Note: when combining fractions, find a common denominator between both fractions

OpenStudy (x3_drummerchick):

12 would be the LCD or "least common denominator"

OpenStudy (anonymous):

Do we keep the negative on the 5/6?
