Village populations (in thousands) are to be drawn as a bar graph: A 8, B 12, C 5, D 15. Every bar must be a whole number of units tall. Which of these scales is the ONLY one that gives every bar a whole-number height? 1 unit = ? thousand

Question

Accepted Answer

1 thousand. The values are 8, 12, 5, 15 — their only common whole-number divisor that makes every bar a whole number of units is 1. With 1 unit = 1 thousand, heights are 8,12,5,15 (all whole). Other scales (5, 8, 12) fail for at least one value.
