| numerator | The number written above the fraction bar of a fraction. It represents how many parts of a total there are. |
| denominator | The number written below the fraction bar in a fraction. It represents the number of equal parts into which a whole is divided. |
| fraction | A ratio, in which the two numbers are related in a part-to-whole relationship. |
| percent | Percent means "out of 100." We can use the percent symbol (%) as a handy way to write a fraction with a common denominator of 100. |

| hundredths | When something is divided into 100 equal parts. |
| decimal | Numbers and arithmetic based on the number ten, tenth parts, and powers of ten |
| PEMDAS | When expressions have more than one operation, we have to follow rules for the order of operations: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. The mnemonic PEMDAS is used to help remember the correct order. |
| common factor | Factors that are common to two or more numbers are said to be common factors. |
