x=6; y=9

Step-by-step explanation:

First, you do the easiest one. For me its y/12=3/4 because you can easily find y. the denominator of y/12 is 12, and the denominator of 3/4 is 4. Since they are equal, then you should divide 12 by 4 to find how many times you have to multiply 3/4 to get y/12. You should get 3, so 3*3 is 9. 9/12=3/4. To check that, you simplify 9/12 and you will get 3/4.

Next step. Now that you know y, you can easily solve x. since y=9, then x=6 because 2*3=6 and 3*3=9. To check, 6/9 simplified is 2/3.

So x=6,y=9.

hope this helped! :D
