Express a fictional plan change as a percentage
About 18 minutes, plus any extended practice
Supplied materials
- Paper or a text document; all cases below are original fictional learning inputs.
- An adult may read aloud; drawing or spoken answers are valid. No personal health information or physical performance is required.
- The separate worked case gives newMinutes=25, oldMinutes=20. Compute(new−old)/old×100 using the original duration as denominator. First identify the quantities and keep their units consistent. The calculation is (25-20)/20*100=25 percent change. Round to six decimal places where needed. That result answers this supplied planning question only. It does not establish what a real person did, diagnose a condition or prove physical skill. Compare the units with the question before accepting a number.
- Fictional case 1: newMinutes=12, oldMinutes=10. What is the modeled result using the stated method?
- Fictional case 2: newMinutes=30, oldMinutes=25. What is the modeled result using the stated method?
- Fictional case 3: newMinutes=18, oldMinutes=15. What is the modeled result using the stated method?
- Fictional case 4: newMinutes=24, oldMinutes=20. What is the modeled result using the stated method?
- Fictional case 5: newMinutes=15, oldMinutes=12. What is the modeled result using the stated method?
- Fictional case 6: newMinutes=35, oldMinutes=28. What is the modeled result using the stated method?
Learn the idea
A relative change uses the old value as the denominator. A five-minute increase means different percentages when the starting plan is ten versus twenty minutes. The percentage describes the supplied change; it is not a safe-progression prescription.
Subtract old from new, divide by old and multiply by one hundred. Keep both the absolute and relative change when explaining. A claim that any fixed percentage prevents injury would exceed this calculation and the supplied evidence.
Use fictional schedules only. No physical test, wearable device or personal fitness record is needed. A plan can be reduced or adapted for access and support. Actual safety depends on more than duration and requires appropriate real-world oversight.
- Mark the facts or constraints in the supplied case.
- Apply the method explained above; draw a sequence, table or decision map.
- Compare your result with the worked solution and explain the difference.
- Complete the new cases, then check the changed-case extension.

Helpful tips
- Relative increase uses the original value, not the new value.
- A percentage calculation is not a safe training limit or injury guarantee.

20 percent change
Compute(new−old)/old×100 using the original duration as denominator. With newMinutes=12, oldMinutes=10, calculate (12-10)/10*100=20 percent change. Results are rounded to six decimal places where needed. This is a supplied model, not a personal health assessment.
Take it further
Changed case: newMinutes=22, oldMinutes=20. Show the operation. Expected: (22-20)/20*100=10 percent change; round to six decimal places where needed, retain model limits and explain the units.
