  4. Bell Work Hakeem’s front porch measures 9 3/4 feet by 4 feet. Estimate the area of his front porch. Justify and illustrate your solution path. (Hint: Area = Length x Width)

  5. 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 the greatest of the common factors of two or more numbers Greatest Common Factor- Improper Fraction- a fraction with a numerator that is greater than or equal to the denominator a number that has a whole number part and a fraction part Mixed Number- Numerator- • the top number of a fraction (the part) Product- • the answer to a multiplication equation Quotient- • the answer to a division equation two numbers with a product of 1 (flipped upside down) Reciprocal – Scaling- to increase or decrease a ratio a fraction in which the GCF of the numerator and denominator is 1 Simplest Form-

  6. Multiplying Fractions(Review) Essential Understanding: • To multiply a fraction by a fraction, you simply multiply the numerators, then the denominators. • 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 the denominators. • Write each product in simplest form. • Quick Check: Complete problems 1-6 on page 104

  7. I Can…. Divide Fractions.

  8. 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 Examples: Quick Check: Complete problems ___ on page ____
