Hey there! :D
We are basically trying to find fractions that equal each other.
3/12= 1/4 4/16= 1/4
The first option applies.
5/8= 5/8 (simplest form) 8/15= 8/15 (simplest form)
The second does not apply.
1/6= 1/6 (simplest form) 5/30= 1/6
The third option does apply.
18/12= 3/2 3/2=3/2 (simplest form)
The fourth option does apply.
The first, third, and fourth option are the answers.
I hope this helps!

Answer:
x=2
z=80
Step-by-step explanation:
Since (7x+66) and (11x+78) are a linear pair, their measures are supplementary and therefore add up to 180 degrees. z and (7x+66) are also vertical angles, meaning that they are equal.
7x+66+11x+78=180
18x+144=180
18x=36
x=2
z=7x+66=7(2)+66=14+66=80
Hope this helps!
