Fractions • Decimals • Percents
With your kind teacher Mrs. Brenda ❤️
Probability can be written in three different ways: as a fraction, a decimal, or a percent. They all mean the same thing — just different ways to show the chance!
| Fraction | Decimal | Percent |
|---|---|---|
| 1/2 | 0.5 | 50% |
| 1/4 | 0.25 | 25% |
| 3/5 | 0.6 | 60% |
| 7/10 | 0.7 | 70% |
To change fraction to decimal → divide numerator by denominator
To change decimal to percent → multiply by 100
Question 1
A spinner has 5 equal sections. 2 are green. Write the probability as a fraction, decimal, and percent.
Question 2
The probability of rain tomorrow is 0.75. Write it as a fraction and a percent.
Question 3
If the probability is 1/5, what is it as a percent?
• Weather apps show “60% chance of rain”
• Lottery tickets show winning chances
• Sports announcers say “75% free throw success”
• Doctors talk about “50% chance of recovery”
Amazing job! You can write probability as fractions, decimals, and percents.
Next time you hear “50% chance”, you’ll know exactly what it means!
Love and lucky high-fives,
