So we're looking for the ratio from the right side, Coils, to the left side, Springs.
I'll set up proportions opposite to the table above to understand the question better.
14:2
28:4
Divide 14 by 2 and 28 by 4 to see if we have a multiplier.
7:1 is our ratio from coils to springs.
A.) is INCORRECT, as it is the opposite of what our answer is, so we need to find a proportion that simplifies to 7coils:1spring.
B.) simplifies to 1 coil, 7 springs, the same as A.), incorrect.
C.) Simplifies 7 coils to 1 spring.
C.) is your CORRECT answer.
:) hope this helps
