Answer:
In absolute terms, you have grown 9 inches (69 - 60).
In relative terms, your growth can be expressed as a percentage increase. To calculate this, we can use the formula:
(relative increase) = (absolute increase / original value) x 100%
Using the values given in the problem, we can plug in and solve:
(relative increase) = (9 / 60) x 100%
(relative increase) = 0.15 x 100%
(relative increase) = 15%
So in relative terms, you have grown 15% since you were 60 inches tall three years ago.
