Digit 
Any number 1 through 9 and 0 

Place Value 
The value of the position of a digit in a number 

Product 
The answer to a multiplication problem 

Dividend 
The number being divided 

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 
The smallest multiple that two numbers share 

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
