True or not? Percentages
You learn to check statements about percentages.
How to work it out
- Work out the percentage yourself using 10% or 1%.
- Or turn it into a fraction you know: 50% is half, 25% is a quarter.
- Then compare with what it says.
True or not? 25% of 80 is 20.
- 25% is a quarter.
- A quarter of 80 is 80 ÷ 4 = 20.
- The statement also says 20.
- So it is true.
