I think it is 3 tbh but i don't wanna get it wrong

3. phi

order of operations. up "top" first do the multiplications what do you get ?

4. anonymous

Well 9x3= 27 and 3x5= 15 The 27-15= 12

5. anonymous

Wait i think i got it now

6. phi

now you have 12/4

7. anonymous

yeah So 3 is right. Sorry just wanna be sure because i keep getting these types of problems wrong.

8. phi

another way (if you know how to do this) is $\frac{9 \cdot 3 - 5 \cdot 3}{4} = \frac{3(9 - 5 )}{4}$ where you "factor out 3" from each term. now we do 9-5 first. we get $\frac{3(9 - 5 )}{4} = \frac{3\cdot 4}{4}$ then we divide 4 by 4 and get $\frac{3\cdot 4}{4}=3$

Oh okay, Thanks for the help
