Practice question · Estimate
On the same frame 36 millimetres wide, how far from the left edge does the nearer golden-section division fall, in millimetres?
Estimate on a scale from 0 mm (0) to 36 mm (36).
Hints
- Divide 36 by 1.618 to find the larger part.
- The larger part measured from the right leaves the smaller part on the left.
Show the answer
13.75 (answers within ±1.5 count)
Why
About 13.75 mm. Dividing 36 by 1.618 gives 22.25, the larger part; measured from the left the nearer division therefore sits at 36 minus 22.25. It lands under two millimetres from the third, a gap the eye cannot see at this scale, which is the honest verdict on the whole dispute.
