Answer: C
Step-by-step explanation:
![\frac{3a}{4}+\frac{2a}{3}-\frac{a}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B3a%7D%7B4%7D%2B%5Cfrac%7B2a%7D%7B3%7D-%5Cfrac%7Ba%7D%7B12%7D)
Find the least common denominator of 4, 3, and 12.
4-3-12 | 3
4-1-4 | 4
1-1-1 |-------- 12
The first fractions needs to be multiplied by 3, and the second fraction, by 4
![(\frac{(3a)*3}{(4)*3})+(\frac{(2a)*4}{(3)*4})-\frac{a}{12}](https://tex.z-dn.net/?f=%28%5Cfrac%7B%283a%29%2A3%7D%7B%284%29%2A3%7D%29%2B%28%5Cfrac%7B%282a%29%2A4%7D%7B%283%29%2A4%7D%29-%5Cfrac%7Ba%7D%7B12%7D)
