H + p = 25
1.50 h + 0,50 p = 26.50
___________________
p = 25 - h
1.50 h + 0.50 ( 25 - h ) = 26.50
1,50 h + 12.50 - 0.50 h = 26.50
h = 26.50 - 12.50
h = 14
p = 25 - 14
p = 11

Answer:
1 2/9
Step-by-step explanation:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
−112÷−92
Applying the fractions formula for division,
=−11×22×−9
=−22−18
Simplifying -22/-18, the answer is
=129
