Ratio of x to y=x/y
1) we have to find out the value of "x" or "y",
--if we find out the value of x, for instead:
2/3=x/(3x+y)
least common multiple: 3(3x+y)
2(3x+y)=3x
6x+2y=3x
6x-3x=-2y
3x=-2y
x=-2y/3
Therefore: ratio of x to y = x/y=(-2y/3) / y=-2/3
Answer: B. -2/3
---if we find out the value of "y",
2(3x+y)=3x
6x+2y=3x
2y=3x-6x
2y=-3x
y=-3x/2
The ratio of x to y = x/y=x / (-3x/2)=-2/3
Answer: B. -2/3
