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!

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!

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

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

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!

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.
