"Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years)." answer: "r = 65 - 60p"

"Rewrite the equation from Part D by factoring the side that contains the variable p." answer: "r = 5 (13 - 12p)"

"Solve the equation for p to find Paula’s age. Express her age (in years) as a fraction." "answer: p = -1/60r + 12/12"

thingy i need help with is "How many months old is Paula?"

What is the Meaning of P
P - 6 = -5

Nico and Lorena used different methods to determine the product of three fractions.

Nico’s Method
Lorena’s Method
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over 30 EndFraction = Negative StartFraction 4 over 15 EndFraction
(2) (one-sixth) (Negative four-fifths) = (StartFraction 2 over 1 EndFraction) (one-sixth) (negative four-fifths) = StartFraction (2) (1) (negative 4) over (1) (6) (5) EndFraction = Negative StartFraction 8 over Negative 30 EndFraction = StartFraction 4 over 15 EndFraction

Whose solution is correct and why?
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over negative 5 EndFraction.
Nico is correct because he knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction.
Lorena is correct because she knew that Negative four-fifths = StartFraction negative 4 over 5 EndFraction
Lorena is correct because she knew that Negative four-fifths = StartFraction negative 4 over negative 5 EndFraction
