Answer:
3
Explanation:
We are given that
![(3abc)/(abc)](https://img.qammunity.org/2019/formulas/mathematics/high-school/mhzeu09zpa71cwxau2rq74qfxyi0xulkue.png)
where abc does not equal to zero.
We have to find simplified of given fraction using properties of real numbers
![(3abc)/(abc)](https://img.qammunity.org/2019/formulas/mathematics/high-school/mhzeu09zpa71cwxau2rq74qfxyi0xulkue.png)
![=(3\cdot 1)/(1)](https://img.qammunity.org/2019/formulas/mathematics/high-school/g6s6irn7ljpufijlx2rcb1wbcnbgvcmjub.png)
abc in numerator and denominator are cancel out to each other.
![(3abc)/(abc)=3* 1=3](https://img.qammunity.org/2019/formulas/mathematics/high-school/vpiyclmoqfx4dty1lc2s4pakd9o28af65b.png)
When a number is multiplied by 1 then we get a number itself.It is identity property of multiplication.
Hence,
![(3abc)/(abc)=3](https://img.qammunity.org/2019/formulas/mathematics/high-school/ld36k4peel48qfyvk2cixhkljxwjms9iw0.png)
