How do you convert a decimal to a percentage?
A percentage means per hundred.
Because 1 is equal to 100%, you convert a decimal to a percentage by multiplying by 100.
Then write the answer with a percent sign.
- Multiply by one hundredMultiply by 100 because 1 is equal to 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.
