Answer:
The pair of fractions with the smallest common denominator is;
![(9)/(12)\text{ and }(4)/(12)](https://img.qammunity.org/2023/formulas/mathematics/college/dv5qdyld77sjkakba1jnttxayvoi1m2zlh.png)
Step-by-step explanation:
Given the fractions;
![(3)/(4)\text{ and }(1)/(3)](https://img.qammunity.org/2023/formulas/mathematics/college/121ikax7knmp3a6axo0h7rqfkojp5e52yz.png)
To write it as a pair of fractions with the smallest common denominator, let us find the least common multiple of the denominator of the fractions.
![\text{LCM = 3}*4=12](https://img.qammunity.org/2023/formulas/mathematics/college/ksaibvex7cg86mvou31bbm0jgrpoie5z2a.png)
expressing the fractions with a denominator of 12;
![\begin{gathered} (3)/(4)=(3(3))/(3(4))=(9)/(12) \\ (1)/(3)=(4(1))/(4(3))=(4)/(12) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/o81mc11lpccwl0iwq5olmlbsztwyabxm47.png)
Therefore, The pair of fractions with the smallest common denominator is;
![(9)/(12)\text{ and }(4)/(12)](https://img.qammunity.org/2023/formulas/mathematics/college/dv5qdyld77sjkakba1jnttxayvoi1m2zlh.png)
