Answer:
3/9
Explanation:
![(1)/(4)\cdot(4)/(4)=(4)/(16)\\\\(1)/(4)\cdot(2)/(2)=(2)/(8)\\\\(1)/(4)\cdot(15)/(15)=(15)/(60)](https://img.qammunity.org/2022/formulas/mathematics/high-school/jge5hgn8h3wrq18ghpnidmpab18vjxq86c.png)
We can turn 1/4 into all of the first three fractions by multiplying it by some version of 1, but we can't do the same for 3/9: trying to multiply 1/4 by 3/3 will get us a different fraction: 3/12. Additionally, 3/9 in lowest form is 1/3, and 1/3 is clearly not equal to 1/4.
