Comparing Percentages, Fractions, and Decimals

Maria, a mathematician, explains how to compare fractions, percents, and decimals by converting them into a common format. She demonstrates converting decimals and fractions into percents and then compares them to determine the order from least to greatest.

What is the first step in comparing fractions, percents, and decimals?

• Convert all values to percents

• Convert all values to a single format

• Convert all values to fractions

• Convert all values to decimals

Why is it important to convert all values to a single format?

• To simplify the process

• To follow mathematical rules

• To ensure accurate comparison

• To make calculations easier

How do you convert a decimal to a percent?

• Move the decimal point two spaces to the left

• Move the decimal point one space to the left

• Move the decimal point one space to the right

• Move the decimal point two spaces to the right

What is 0.6 as a percent?

• 0.6%

• 600%

• 60%

• 6%

What is the easiest way to remember the direction to move the decimal point when converting to a percent?

• Think of the alphabet from D to P

• Think of the alphabet from P to D

• Move left for decimals

• Move right for fractions

What is the equivalent percent of 3/4?

• 25%

• 100%

• 50%

• 75%

How do you convert a fraction to a percent?

• Divide the denominator by 100

• Multiply the numerator by 100

• Convert to a decimal first, then to a percent

• Multiply both numerator and denominator by 100

What is the equivalent percent of 1/2?

• 25%

• 50%

• 75%

• 100%

What is the final step after converting all values to a single format?

• Multiply all the values

• Subtract the smallest value from the largest

• Compare the values

• Add all the values
