Answer:
[tex]\frac{1}{7}[/tex]
Explanation:
[tex]\frac{3}{17} *\frac{17}{21}[/tex]
[tex]\frac{3*17}{17*21}[/tex]
[tex]\frac{51}{357}[/tex]
357 is divisable by 51
[tex]\frac{1}{7}[/tex] is the lowest term. You can also see that because there is a 17 on top and a 17 on bottom so they cancel. You're left with 3/21 which reduces to [tex]\frac{1}{7}[/tex]
