Here is the answer With working
If you are saying:
(3/12) - (8/12)
Then since their denominators are the same we can subtract the numerators to get our answers.
3 - 8 = -5
Following the rule of adding and subtracting fractions, the denominators will not change unless they are different.
So: (3/12) - (8/12) = -5/12
Answer:
p = 
Step-by-step explanation:
change the mixed number to an improper fraction
- 2 
= - 
, hence
- p = - 3 ( multiply both sides by 7 )
- 15p = - 21 ( divide both sides by - 15 )
p = 
=
