I will be your tutor. /$\frac{ 4 }{ 3 } = \frac{ x }{ 12 }$ The first step to solving the equation is to cross-multiply all terms. Can you do that for me?

3. anonymous

so is that 4*12 then 3*x ?

4. Compassionate

Correct! Can you write out the new equation?

5. anonymous

isn't that the equation though?

6. Compassionate

Now. The new equation is: $48 = 3x$

7. anonymous

ohh. okay. so then x = 16 ?

8. Compassionate

Yup, that's correct!

9. anonymous

so then how do i get the answer for this?
