Relative ages – who is oldest and gets the extra slice? Randy is 2 months older than Greg. Greg is 3 months younger than Ned. Kent is 1 month older than Greg. The oldest gets the extra piece. Who is it?

Introduction / Context:
This is a simple relative-age comparison. Converting all ages to differences from a single baseline makes it easy to rank the four friends by age and identify the oldest.

Given Data / Assumptions:

• Randy = Greg + 2 months.
• Greg = Ned − 3 months (i.e., Ned = Greg + 3 months).
• Kent = Greg + 1 month.
• Oldest friend receives the extra pizza slice.

Concept / Approach:
Use a reference variable for Greg’s age and express all others in terms of Greg. Then compare the offsets to determine who has the largest value (oldest).
