What Will Students Learn in Fractions in Disguise?
A student who finishes Fractions in Disguise Class 8 should be able to do these things:
- Express a fraction as a percentage by multiplying it by 100%.
- Convert a percentage into a fraction in simplest form.
- Recognise equivalent fractions, such as 24% = 24/100 = 6/25.
- Handle percentages above 100%, such as 7/4 = 175%.
- Compare quantities using percentages instead of fractions with different denominators.
- Apply Fractions in Disguise Class 8 ideas to marks, discounts and surveys.
How to Convert a Fraction to a Percentage in Fractions in Disguise
To convert a fraction to a percentage, multiply the fraction by 100%. This one rule solves most Fractions in Disguise Class 8 questions.
- Write the fraction, for example 3/8.
- Multiply by 100%: 3/8 × 100% = 300/8 %.
- Simplify: 300 ÷ 8 = 37.5, so 3/8 = 37.5%.
The table below applies the same rule to five common fractions from a typical Fractions in Disguise worksheet.
| Fraction | Working (multiply by 100%) | Percentage |
|---|---|---|
| 3/5 | 3/5 × 100% = 300/5 % | 60% |
| 9/20 | 9/20 × 100% = 900/20 % | 45% |
| 3/8 | 3/8 × 100% = 300/8 % | 37.5% |
| 7/4 | 7/4 × 100% = 700/4 % | 175% |
| 1/3 | 1/3 × 100% = 100/3 % | 33⅓% (33.33…%) |
Notice that 7/4 gives 175%. In Fractions in Disguise Class 8, a percentage above 100% simply means “more than the whole”.
How to Convert a Percentage to a Fraction
To convert a percentage to a fraction, write the percentage over 100 and simplify. This is the reverse of the rule above, and it is the second big skill in Fractions in Disguise Class 8.
- 24% = 24/100 = 6/25
- 35% = 35/100 = 7/20
- 12.5% = 12.5/100 = 125/1000 = 1/8
- 150% = 150/100 = 3/2
Always divide the numerator and denominator by their common factor. An unsimplified answer loses marks in Fractions in Disguise Class 8 exams.
Where Fractions in Disguise Shows Up in Real Life
Fractions in Disguise Class 8 is useful far beyond the exam hall. Here are four everyday places where fractions hide as percentages:
- Exam marks: 36 out of 40 is 36/40 = 9/10 = 90%.
- Discounts: a ₹800 shirt with 25% off saves 1/4 × 800 = ₹200.
- Phone battery: a battery that is 3/5 full shows 60%.
- Surveys: 15 of 40 students in the school band is 15/40 = 3/8 = 37.5%.
Spotting these links makes Fractions in Disguise Class 8 feel practical, not just procedural.

Common Mistakes in Fractions in Disguise (and How to Fix Them)
Most lost marks in Fractions in Disguise come from five small slips. The table shows each mistake and its fix.
| Mistake | Example | How to fix it |
|---|---|---|
| Forgetting to multiply by 100 | Writing 3/5 = 3/5% | ✓ Multiply by 100%: 3/5 × 100% = 60% |
| Not simplifying the fraction | 35% = 35/100 | ✓ Divide by 5: 35/100 = 7/20 |

| Believing a percentage cannot exceed 100% | 7/4 “cannot” be a percentage | ✓ 7/4 × 100% = 175%, which is more than the whole |
