  • Han cuts a 15-foot piece of rope into 4 equal parts. TRUE or FALSE: the expression 15 ÷ 4 represents the length of each part of the rope in feet.
    True, this is 1 of four equal groups making 15.
  • How do you reduce fractions?
    Find Greatest Common Factor (GCF) for the numerator and the denominator. Then, divide the numerator and denominators by the GCF.
  • Han cuts a 15-foot piece of rope into 4 equal parts. TRUE or FALSE: the expression 4 x 15 represents the length of each part of the rope in feet.
    False, this is 4 times as long as the piece of rope.
  • What is the math term for the answer to a multiplication expression?
    Product
  • Explain how to multiply fractions by a whole number.
    Put the whole number over 1. Next, multiply the numerators together to find the product's numerator. Then, multiply the denominators to find the product's denom
  • What is the math term for the answer to a division equation?
    Quotient
  • Han cuts a 15-foot piece of rope into 4 equal parts. TRUE or FALSE: the expression 3 ¾ represents the length of each part of the rope in feet.
    True, 12 feet of the rope gives 4 equal groups of 3 and then there are 3 feet left and dividing that into 4 equal parts is ¾ more feet.
  • ⅛ x 11
    11/8
  • What is a divisor?
    The number doing the dividing is called the divisor. This numberwill divide the dividend exactly.
  • 1/7 x 6
    6/7
  • What is a dividend?
    The number being divided is called the dividend.
  • Explain the difference between a factor and a multiple.
    Factors are the numbers multiplied to get a product. Multiples are the sequence of factors (skip counting).
  • ⅓ x 34
    34/3 (also acceptable: 11 ⅓)
  • ½ x 6
    6/2 (also acceptable: 3)
