Lesson 10: Problem Solving with Fraction Operations
Math Vocabulary: terms will be added as we go. It is important to ;learn the language of math!
addend: the number you add to one or more other numbers
benchmark: a familiar number used as a point of reference
common denominator: when two or more factions have the same denominator. Adding and Subtracting fractions requires common denominators.
common factor: a number that is a factor of two or more numbers
compatible numbers: Numbers that can be divided evenly. Used in estimating division
decimal: a part of a whole number expressed in tenths, hundredths, thousandths, etc.-placed after a decimal point. (powers of ten)
denominator: it is how many parts a whole number is divided into. The bottom number of a fraction. When adding and subtracting, you must first make common denominators.
difference: the answer to a subtraction problem
dividend: the number that is to be divided in a division problem
divisor: the number that divides the dividend
equivalent fractions: two or more fractions that name the same amount
factor : one or more numbers that are multiplied together to get a product
Fraction: part of a whole number with a numerator and a denominator
Greatest Common Factor (GCF): used when simplifying fractions. The largest factor that two or more numbers have in common
Inverse operations: operations that The largest f another one. Adding and subtracting are inverse operations as are multiplying and dividing.
Least Common Multiple (LCM): number that is smallest (least)common multiple of two or more numbers:
mixed number a number represented by a wholenumber and a fraction
multiplicative inverse one of two numbers whose product is 1
numerator: The number of parts of the divided whole number. it is the top of the fraction, the numerator. Tells how many fractional parts there are
prime factorization: a number written as the product of all of its prime factors
prime number: a number that has exactly two factors : 1 and itself
product: the answer to a multiplication problem
quotient: the answer to a division problem
reciprocal:one of two numbers whose product is 1
simplest form a fraction in which 1 is the only number that can divide evenly into the
numerator and the denominator
sum: the answer to an addition problem
