The common denominator is 4
Explanation:
To answer this question of what is
![(1)/(4) +(1)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/vbsm6m5su4yl8n0oz2hplhtc2n60ygfte1.png)
We first have to find the LCM(Least Common Multiple) of the unlike denominators 4 and 2 which is 4
So we multiply the numerator and denominator
by 2 so we can add with the same denominator
![(1*2)/(2*2)=(2)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/ivxkrj6qgsr14aprbjf3w4x3r9q98mczvz.png)
