4:6:2
this is because 2+3+1 is 6 and you divide that by 12 which is 2 and you times 2 to every ratio
D is the correct equation for this problem.
Answer:
0
Step-by-step explanation:
3x = 2
x = 2/3
plug in
12/3 - 4
4 - 4
=0
We will write it as a fraction in ordet to solve, that is:

We then operate as follows:

We have this, since 1 integer will be equal as a numerator divided by a denominator with equal values. Examples 1 = 2/2, 1 = 45/45, ...
3(x)-5=x+5
3x=-5+5+x
3x=x
0=x
because 3x=x is basically would make each part into 0 which would end up the same.
