Percentages · Grade 6
In Grade 6 you learn: percentages of amounts; percentages as fractions and decimals.
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%.
- Working backwards: if 30% is 42, then 1% is 1.4 and 100% is 140.
- The percentages that make up a whole add up to 100%.
