Percentages, Fractions, and Decimal Values
Percentages are defined as a fraction or portion of a whole. Generally percentages deal with an amount out of one hundred but can be used in sales, economics, and science. If you've walked into any store you're sure to find something marked a certain percent off. Fractions are not whole numbers with a numerator over a denominator. Usually the numerator and denominator are expressed as integers. There are four types of fractions: simple fractions, complex fractions, mixed fractions, and improper fractions. Decimals are also not integers. They are expressed often like 0.34 and are often rounded off since some go for too long. Both decimals and fractions are also used to convert to percentages.

How do you calculate a percentage change increase or decrease?
The simplest rule to never get confused:
Always divide by the ORIGINAL value.
Percent increase formula:
(New - Old) / Old × 100
Percent decrease formula:
(Old - New) / Old × 100
Notice the bottom number is always the starting value.
Example:
Price goes from 200 to 250
Difference = 50
50 / 200 = 0.25
0.25 × 100 = 25% increase
Another example:
100 to 80
Difference = 20
20 / 100 = 0.20
So 20% decrease
But going from 80 to 100 is NOT 20% increase
20 / 80 = 0.25
So it's actually 25% increase
That’s where most people get confused — they divide by the wrong base.
Quick mental trick:
Find what fraction the difference is of the original.
If 20 is one-fourth of 80, then it’s 25%.
If you want to double check while practicing, you can use a calculator like this:

What is a mixed status family?
A mixed-status family is a household where members have different immigration statuses, which may include a combination of citizens, lawful permanent residents, and undocumented immigrants. This situation often arises in families where some members were born in the U.S. while others immigrated from different countries.
