### QUIZ QUESTIONS LISTED AT END OF REVIEW Conversion questions are directly and indirectly asked throughout the ATI TEAS. The exam will ask applicants to take one value and create the same value in a different form. Conversion questions can include decimals to percentages, fractions to percentages, and fractions to decimals. It’s important to understand how to convert these operations to answer most mathematic questions throughout the exam.

## CONVERTING DECIMALS AND PERCENTAGES

To convert a percentage to a decimal, move the decimal point to the left two place values.

For example: 30.5% = 0.305

**Remember to always add a zero before the decimal point if there is no place value. This will help prevent medication errors in the future.

To convert a decimal to a percentage, move the decimal point to the right two place values.

For example: 0.543 = 54.3%

## CONVERTING FRACTIONS AND DECIMALS

To convert a fraction into a decimal, divide the numerator by the denominator.

For example: 4/16 = 0.25

To convert a decimal to a fraction is a three-step process.

Step 1: Remove the decimal point

For example: 0.25 -> 25

Step 2: Use the converted number as a numerator

For example: 0.25 = 25/denominator

Step 3: Add 100 in the denominator portion of the fraction

For example: 0.25 = 25/100

Step 4 (optional): Simply the fraction. Some questions will ask for you to simplify the fraction.

For example: 25/100 = ¼

## CONVERTING FRACTIONS AND PERCENTAGES

In order to convert a fraction to a percentage, we must first convert the fraction to a decimal. Next, move the decimal two place values to the right.

For example: 1/4 = 0.25 = 25%

Converting a percentage to a fraction is a three-step process.

Step 1: Move the decimal place value two places to the right

25% = 0.25

Step 2: Remove the decimal and place the remaining number in the numerator of a

fraction

0.25 = 25 = 25/denominator

Step 3: Divide the remaining number by the denominator 100

25/100

Step 4 (optional): Simply the fraction. Some questions will ask for you to simplify the fraction.

25/100 = 1/4
