Percentages · Grade 5
In Grade 5 you learn: per cent as "out of 100".
Per cent means “out of 100”, so 35% means 35 out of every 100. Percentages make it easy to compare discounts, test scores, interest rates and survey results, even when the totals are different.
Key facts
- 50% = a half, 25% = a quarter, 10% = ÷ 10, 1% = ÷ 100.
- Build other percentages from these: 35% = 10% + 10% + 10% + 5%.
- The percentages that make up a whole add up to 100%.
