Sample: the first question, solved
Which is easier to compare at a glance: "18 out of 40" or "45%"?
📘 Worked solution
✓45% is easier - it's already converted to a standard out-of-100 scale, so no extra calculation is needed to compare it to other percentages.
And one from the hard end
Design a comparison: City A (12,000 residents) reports "18% recycle regularly"; City B (150 residents) reports "40% recycle regularly." Explain why City A's lower percentage might still represent a more reliable and larger overall recycling effort.
