1. 60 is 20% of 100
- False po, because when you multiply 20% by 100, the result will be 20. If you convert 20% to decimals, the result will be 0.2. So, 0.2 × 100 = 20. The answer to the equation is 60, so they are different and the true answer is 20, So he became false.
2. 50% of 10 is 5
- True po, Because when you multiply 50% of 10, the result will be 5. If you convert 50% to decimals, the result will be 0.5. So, 0.5 × 10 = 5. The answer to the equation is 5, So they are same, So he became true.
3. 40% of 60 is 24
- True po, Because when you multiply 40% of 60, the result will be 24. If you convert 40% to decimals, the result will be 0.4. So, 0.4 × 60 = 24. The answer to the equation is 24, So they are same, So he became true.
4. 20% of 140 is 28
- True po, Because when you multiply 20% of 40, the result will be 28. If you convert 20% to decimals, the result will be 0.2. So, 0.2 × 140 = 28. The answer to the equation is 24, So they are same, So he became true.
5. 18 is 15% of 45
- False po, because when you multiply 15% by 45, the result will be 6.75. If you convert 15% to decimals, the result will be 0.15. So, 0.15 × 45 = 6.75. The answer to the equation is 18, so they are different and the true answer is 6.75, So he became false.

- 1. When we see the word "of", it is what we multiply and when we see the word "is", this is the answer. Example: 15% of 10 is 1.5. 15% it will be 0.15. 0.15 × 10 = 1.5.
- 2. When we answer this, we will always use the formula that: P = B × R.
Example:
10% of 10 is 1
- 10% Convert to decimals = 0.1, as P.
- 0.1 as B
- 10 as R.
So, its formula is P = B × R.
