9, because you should multiply by (7-4)
It depends if you multiply or divide by (7-4)
It could be
[tex]\frac93(7-4)=3(3)=9[/tex]
Or it could be
[tex]\frac9{3(7-4)}=\frac9{3(3)}=\frac99=1[/tex]
I think it's 9. I'd divide by 3 and then multiply by (7-4). If I meant to divide by 7-4 I'd write 9÷3÷(7-4)
