5.3I Multiplying Fractions

5.3(I) Represent and solve multiplication of a whole number and a fraction that refers to the same whole using objects and pictorial models, including area models.

• Today's Objective: We will solve multiplication of a whole number and a fraction that refers to the same whole.

Key Vocabulary for TEK 5.3I Multiplying Fractions

• Fraction- a numerical quantity that is not a whole number (e.g. 1/2, 0.5). or a small or tiny part, amount of something.

• Whole numbers- Any of the numbers {0, 1, 2, 3, ...} etc.

  
  

  There is no fractional or decimal part. And no negatives.

  
  

  Example: 5, 49 and 980 are all whole numbers.
