III. Procedure:
A. Activity
1. Preliminary Activities
a. Review
Complete it!
To sum it up, let us complete the statements. Choose your answer from the box that best
completes the statements below.
improper
numerator
division
reciprocal
multiply
simplify
1. To find the product of fraction, we simply multiply the ______________ and multiply the
denominators.
2. To find the product of mixed numbers, change them to improper fraction and then
___________.
3. If the given is a mixed fraction, change to __________ fraction and follow the first rule.
2. Activity Proper

B. Analysis
a. How did you find the activity?
b. How did you fill in the blanks/boxes with the correct number?
c. What operations were used during the activity?
d. Can you provide the steps in dividing fractions? What are these?
So today we are going to divide fractions (similar, dissimilar and mixed numbers)
C. Abstraction
Division of fractions
a. To divide fractions, multiply the dividend by the multiplicative inverse (reciprocal) of the divisor.
b. If the given is a mixed fraction, change to improper fraction and follow the first rule.
1. Find the quotient: 2/3 ÷ 1/2
= (2/3)(2/1) Multiply the dividend to the multiplicative inverse of the divisor
= 4/3 or 1 1/3 Change to mixed number.
Thus, the quotient is 4/3 or 1 1/3.
2. Find the quotient: 6 2/3 ÷ 1 1/2
= 20/3 ÷ (3/2) Change mixed fraction to improper fraction
= (20/3)(2/3) Multiply the dividend to the multiplicative inverse of the divisor
= 40/9 or 4 4/9 Change to mixed number.
Thus, the quotient is 40/9 or 4 4/9.
3. Consider this situation.
A 20-liter tank is to be filled with water by repeatedly pouring from a can which holds 2
1/2 liters. How many times pouring are needed to fill the tank?
This calls for a division sentence.
20 ÷ 2 1/2 = 20 ÷ 5/2 Change mixed fraction to improper fraction
= 20/1 • 2/5 Multiply the dividend to the multiplicative inverse of the divisor
= 20•2 /1•5 Multiply the fractions
= 40/5 or 8 Simplify
Thus, it requires 8 pouring’s of water to fill the 20-liter tank.
