To find a percentage of a number without a calculator, you can use the method of converting the percentage to a fraction or decimal, and then multiply it with the given number.
1. To find 30% of 500:
- We know that 30% is equal to 30/100 or 0.3.
- Multiply 0.3 by 500:
0.3 * 500 = 150
Therefore, 30% of 500 is 150.
2. To find 0.5% of 3200:
- We know that 0.5% is equal to 0.5/100 or 0.005.
- Multiply 0.005 by 3200:
0.005 * 3200 = 16
Therefore, 0.5% of 3200 is 16.
There is no specific formula for finding percentages without a calculator, but understanding the concept of percentages as fractions or decimals can help in such calculations.
