Are any questions? OPPORTUNITY FOR QUESTIONS: 1. QUESTIONS FROM THE CLASS 2. QUESTIONS TO THE CLASS: Q. What must be done to the divisor when dividing fractions? A. The divisor must be inverted and change the division operation to a multiplication operation. Now that we understand the process of dividing fractions, let’s move on to decimals. (ON #65) Decimals: k. The representation of the fraction whose denominator is some power of ten. (ON SLIDE #66)
