\[p-\frac{ 1 }{ 4 } * 3 = \frac{ 5 }{ 6 }\] 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

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

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?
