Put simply, yes.
To prove, find like denominators, then compare numerators.
Factors of 6: 6, 12, 18, 24, 30, 36
Factors of 8: 8, 16, 24, 32, 40, 48
The LCF is 24.
![(4)/(6)*4=(16)/(24)](https://img.qammunity.org/2022/formulas/mathematics/college/v5qpuacqy19jarwsskxsur9up8kwa7ag6y.png)
![(2)/(8)*3=(6)/(24)](https://img.qammunity.org/2022/formulas/mathematics/college/fweo655371frfr6sxo1e9kmpbwnozc1wir.png)
Now compare numerators.
16 > 6
So yes, 4/6 is greater than 2/8.
Hope this helps. Have a nice day.
