Percent of Change Flashcards

💡Interpret the percent sign as division by \(100\).

💡Move the decimal point two places right.

💡Rates below \(1\%\) need extra care.

💡Find the fraction's decimal value first.

💡The original value is the denominator.

💡Ask what the situation started with.

💡Keep the original \(100\%\) and add the increase.

💡Use the fraction that remains.

💡Do not subtract the rate from the final value.

💡The final value is only a fraction of the original.

💡Each change acts on the current value.

💡The decrease acts on a different base.

💡The comparison is measured relative to \(B\).

💡Divide the difference by \(B\).

💡The two answers have different bases.

💡Convert normally by dividing by \(100\).

💡Dividing by \(100\) adds two decimal places.

💡An increase cannot use a remaining fraction below \(1\).

💡The multiplier represents the fraction remaining.

💡Label the values before subtracting.
