The ratio would be 1:4, I would start with dividing each number by 2 then working from there. With diving by two you would end up with 3:12 which you then can divide by 3 since 12 is divisible by 3. This would get you 1:4.
Answer:
1/(x^(17/12)y^(5/3))
Step-by-step explanation:
We assume you want to simplify the expression. The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
1/a^b = a^-b
Using these "all at once", we can add up the exponents of each of the variables:
x^(-2/3 -2·0 -(1/2)(3/2))·y^(-2/3-(1/2)·2) = x^(-2/3-3/4)y^(-2/3-1)
= x^(-17/12)y^(-5/3)
= 
The measure of angle 1 is 106°, because since it is a straight line they measure would have to add up to 180°.
The answer is 4/7. Hope this helps
