Answer:
[tex] \frac{3}{4} [/tex]
Step-by-step explanation:
Simplifying 9/12 requires factoring out the largest common factors between the numbers, which is 3. Therefore dividing 9 by 3 gives us 3. Similarly, dividing 12 by 3 gives us 4. At this point there is no more common factor (except 1 but is needless here). Thus writing 9/12 in simplest form is 3/4.
