Reading the news
When a report describes a fraction of customers or transactions, find the total population. Converting the share can help interpretation, but an absolute count needs the appropriate base and period.
02 / UNDERSTANDING
The concept in context
Comparisons may use common denominators or cross-products when denominators are positive. Avoid rounding so early that close fractions become indistinguishable. Negative values require particular care because intuition based only on numerator size can fail. For ordinary positive share questions, estimate the fraction’s position between zero and one before computing the exact amount.

A worked learning case
Original educational case. An original practice plan assigns three eighths of 160 questions to arithmetic. One eighth is 20, so three eighths is 60. The fraction equals 0.375 or 37.5%. Writing the base of 160 prevents the learner from treating 37.5% as a fixed number of questions independent of the total workload.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Original practice: What percentage is 3/8?
Show the answer and reasoning
37.5%.
Divide 3 by 8 to obtain 0.375, then multiply by 100 to express it as a percentage. Alternatively, one eighth is 12.5%, so three eighths is 37.5%. The result is below one half, or 50%, which is a quick benchmark confirming that the decimal has been placed sensibly.
Two traps to watch for.
- Treating a fraction’s percentage as an absolute quantity.
- Rounding close fractions before deciding which is larger.

Evidence to check
Recall halves, quarters and eighths.
Convert one fraction three ways.
Check each amount against its named base.
Explain the idea, apply it to a new situation, then check what changed in your reasoning.
