Theory
A percentage is a part of 100.
You can first read a fraction as a division: numerator divided by denominator. Then you get a decimal number.
Multiply that decimal number by 100 and write the result as a percentage.
- Divide numerator by denominatorRead the fraction bar as a division.
Dividing means sharing an amount fairly or seeing how many equal groups fit into it.
The first number is the total amount. The second number tells you what you divide by.
Always check whether the division works out exactly. If it does not, you get a decimal number or fraction as the answer.
- Multiply by one hundredTurn the decimal number into a percentage by multiplying by 100.
You use multiplication with equal groups.
A × B means that you take the same amount B, A times.Instead of adding again and again, you calculate the product all at once.
- Write as a percentagePut a percent sign after the calculated value.
- Divide numerator by denominator1 ÷ 4 = 0,25.
- Multiply by one hundred0,25 × 100 = 25.
- Write as a percentageThe answer is 25%.
