Converting Percents to Fractions

• Every percent has a denominator of 100

• To convert a percent into a fraction, take the percent number and put it over 100

• Don't forget to simplify if possible!

Converting Decimals to Fractions

• When reading a decimal, make sure to use it's official mathematical name!

• Example: 0.1 = "One Tenth, 0.23 = "Twenty Three Hundredths"

• Write what you say as a fraction

• Don't forget to simplify if possible!

Converting Fractions to Decimals

• When converting fractions to decimals, we always divide the numerator by the denominator

• The numerator goes inside the house

• The denominator goes outside the house

Converting Percents to Decimals

• We know that every percent can be written as a fraction over 100

• We know that every fraction is actually a division problem

• Using this knowledge, we know that we can convert percents to decimals by moving the decimal two places to the left

Converting Decimals to Percents

• To convert a decimal to a percent, we just do the opposite of what we did when we converted percents into decimals

• To do this is to move the decimal point two spaces to the right!

Converting Fractions to Percents

• When converting fractions to percents, we have three levels of problems.

• Level 1: If the denominator is already 100, simply put a % after the numerator

• Level 2: Sometimes the denominator can be multiplied or divided to become 100. Whatever you do to the top must be done to the bottom. 

• Level 3: When the denominator cannot be multiplied or divided to become 100, we must divide up. Horse and rider.
