Nona is one-third as old as her mother. Five years ago, she was only one-fifth of the age of her mother. How old is Nona now?

• mother age be x
  nona age bcomes 1/3(x)
  1/3(x)-5=1/5(x)
  by solving we get,
  x=37.5
  and nona is 12.5

• Nona is one-third as old as her mother.
  n = 1%2F3m
  multiply both sides by 3
  3n = m

  Five years ago, she was only one-fifth of the age of her mother.
  n - 5 = 1%2F5(m-5)
  multiply both sides by 5
  5(n-5) = m - 5
  5n - 25 = m - 5
  5n = m - 5 + 25
  
  5n = m + 20
  replace m with 3n
  5n = 3n + 20
  5n - 3n = 20
  2n = 20
  n = 20%2F2
  n = 10 yrs old is Nona's age
