75 is 5/2 of greg's age
greg's age ---- x
(5/2)x = 75
times 2
5x = 150
x = 30
(5/2)x = 75
x = 75 / (5/2)
x = 75 * (2/5)
x = 150/5 = 30
To find Greg's age, we can set up an equation using the information given.
The equation is: 75 = (5/2) * Greg's age
To solve for Greg's age, we can multiply both sides of the equation by 2/5.
(2/5) * 75 = Greg's age
This simplifies to:
30 = Greg's age
Therefore, Greg's age is 30.
