Mary's age is 1/3 of Helen's age. If Mary is 48 years old, how old is Helen?
(1/3)x = 48
x = 48 / (1/3)
x = 48 * (3/1) = 144
Are you sure about this problem? As far as I know, no one has lived to be 144 years old.
To figure out Helen's age, we'll use the information given. We know that Mary's age is 1/3 of Helen's age. So, we can set up an equation:
Mary's age = 1/3 * Helen's age
Given that Mary's age is 48, we can substitute this value into the equation:
48 = 1/3 * Helen's age
To solve for Helen's age, we can multiply both sides of the equation by 3 to eliminate the fraction:
48 * 3 = Helen's age
Simplifying the equation, we get:
144 = Helen's age
Therefore, Helen is 144 years old.
