______ fractions are fractions that represent the same quantity. 

Equivalent  

How could you tell if 11/12 is equal to 5/17? 

Cross multiply

Example: Is 11 times 17 equal to 12 times 5? 

What is 1/2 in decimal form and percent form? 

decimal form: .5

percent form: 50% 

How do you turn a fraction into a decimal? 

Divide the top by the bottom

Reduce the following fraction:

8/24 

1/3

You divide both the top and bottom by the greatest common factor, in this case it was 8. 

Write this number as a percent

1.56 

156%

 You move the decimal two places to the right. 

The _____ ______ _______, or LCD of two or more fractions is the least number that is a common denominator of the fractions. 

Least Common Denominator 

What is the Least Common Denominator of 1/6 and 1/9? 

18

because you take the Least Common Multiple of both denominators, in this case it was 18.

How do you multiply fractions?

Multiply across 

 Ex: 1/9×1/2=(1×1)/(9×2)=1/18

How do you divide fractions? 

Flip the second fraction and multiply across

Ex: 3/4 ÷1/2=(3/4)×(2/1)=6/4

A _____ is a letter or symbol used to represent a value that can change (Usually represented by x).
