\[\huge \frac{ 18 }{ 12 } -->\frac{ 9 }{ 6 } --> \frac{ 3 }{ 2 }\]
OpenStudy (anonymous):
same as reducing \[\frac{18}{12}\]divide top and bottom by the common factor of 6
OpenStudy (shamil98):
Take out the common factors like so. 18/12 both can be reduced by 2, you get 9/6, they can be reduced 3 , you get 3/2
OpenStudy (calculusxy):
An easy way can be to find the GCF of 18 and 12. Factors of 18- 1,2,3,6,9,18 Factors of 12-1,2,3,4,6,12 GCF is 6. You can now divide 18/6=3 and 12/6=2. Now you get the fraction of 3/2.
