Divisor

The number by which the dividend is divided

Quotient

The answer to a division problem

Remainder

The portion of the dividend that is not evenly divisible by the divisor

Decimal

Pertains to the tenths or to the number 10

Place Value

The value of the position of a digit in a number

Multiplication of Decimals

Move the decimal point the number of places to the left as there are in the numbers being multiplied

Division of Decimals

Move decimals over in both the divisor and dividend to create whole numbers, then divide

Fraction

A way to express a part in relation to the total

Numerator

The top number in a fraction

Denominator

The bottom number in a fraction

Fraction Bar

The line between the numerator and denominator; another symbol for division

Factor

A number that divides evenly into another number

Least Common Denominator

Improper Fraction

A fraction where the numerator is larger than the denominator

Proper Fraction

A fraction where the denominator is larger than the numerator

Common Denominator

Two or more fractions having the same denominator

Reciprocals

Pairs of numbers that equal 1 when multiplied together

Terminating Decimal

A decimal that is not continuous

Turning an Improper Fraction into a Mixed Number

The numerator goes in the "box" an the denominator stays out and divide; the number that it divides into becomes the whole number, the remainder becomes the numerator, and the denominator stays the same.

Addition of Fractions with Unlike Denominators

1. Find the LCD of each denominator

2. If the denominator is changed, the numerator must also be changed by the same number by multiplying the numerator and denominator by the same number


3. Add the numerators together, and keep the common denominator


4. Reduce the fraction if necessary

Addition of Mixed Numbers

1. Leave the whole number alone and focus solely on the fraction


2. Find the least common denominator of the fractions


3. If the denominator is changed, the numerator must also be changed by the same number by multiplying the numerator and denominator by the same number


4. Bring back the whole numbers to their designated fraction


5. Add together the whole numbers


6. Add together the numerators and keep the common denominator


7. Reduce the fraction if necessary

Subtracting Fractions with Unlike Denominators

1. Find the LCD of the fractions


2. If the denominator is changed, the numerator must also be changed by the same number by multiplying the numerator and denominator by the same number


3. Subtract the numerators and keep the denominators the same


4. Reduce the fraction if necessary

Multiplication of Fractions

1. Multiply the numerators together


2. Multiply the denominators together


3. Reduce the fraction if necessary

Division of Fractions

1. Write the inverse of the second fraction


2. Multiply the numerators


3. Multiply the denominators (do not find LCD)


4. Reduce the fraction if necessary

Ratio

A relationship between two numbers

Proportion

Two ratios that have equal values

Ways to write Ratios

1. a/b


2. a:b


3. a to b

Ways to write Proportions

1. a/b = c/d


2. a : b :: c : d
