Vocabulary Denominator- the bottom number of a fraction (the whole) Equivalent- equal or the same Fraction- a number that represents part of a whole or part of a set Greatest Common Factor- the greatest of the common factors of two or more numbers Improper Fraction- a fraction with a numerator that is greater than or equal to the denominator Mixed Number- a number that has a whole number part and a fraction part Numerator- the top number of a fraction (the part) Product- the answer to a multiplication equation Quotient- the answer to a division equation Reciprocal – two numbers with a product of 1 (flipped upside down) Scaling- to increase or decrease a ratio Simplest Form- a fraction in which the GCF of the numerator and denominator is 1
Multiplying Fractions (Review) Essential Understanding: To multiply a fraction by a fraction, you simply multiply the numerator by numerator, then the denominator by denominator. To multiply a fraction by a whole number or a mixed number, you must first change the number to an improper fraction. Then, multiply the numerators and then the denominators. Write each product in simplest form. Quick Check: Complete problems 1-6 on page 104
I Can…. Divide Fractions.
Dividing Fractions Essential Understanding: To divide a fraction by a fraction, begin by finding the reciprocal of the divisor (flip the second fraction). Then simply multiply numerator by numerator and denominator by denominator. In other word, Keep Change Flip Examples: To divide a fraction by a whole number or a mixed number, begin by changing the numbers to improper fractions before following the procedure for dividing fractions. In other words …… Keep Change Flip Quick Check: Complete problems ___ on page ____
