This is the simplest proportion i have seen.
This is how we do it:

=

The answer surprisingly is obvious,
z = 1But we can still do cross multiplication
7z = 7
Divide by 7 to isolate z

7 and 7 cancels out
z = 1
Answer:

Step-by-step explanation:
To solve this proportion, we will divide the two given denominators.
Now, we have: 30 ÷ 5 = 6
Next, we will multiply the given numerator by the quotient: 3 × 6 = 18
So, our final proportion will have to be:

Answer:
d doesnot depict a linear relationship as y= mx+c to have linear equation
