Lesson 3: Lesson Three--Greatest Common Factor/Reducing Fractions
Section Two: More on GCF
I will give you some "guided practice" in reducing fractions. First, practice in determining if a fraction can be reduced.
If a fraction can be reduced, put Y for yes and N for no( answers in next section) and see if you can figure out the GCF in fractions that can be reduced:
1. 13/67 2. 12/86 3. 14/98 4. 21/87 5. 45/120 6. 28/119 7. 47/99 8. 26/91 9. 84/95 10. 76/133
Now, reduce these fractions:
1. 5/20 2. 32/56 3. 25/30 4. 90/200
