Question

how do I do this; Express the ratio as a fraction in simplest form. 18 : 12

Answer 1

\[\huge \frac{ 18 }{ 12 } -->\frac{ 9 }{ 6 } --> \frac{ 3 }{ 2 }\]

Answer 2

same as reducing \[\frac{18}{12}\]divide top and bottom by the common factor of 6

Answer 3

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

Answer 4

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.
