To determine which fraction is not equivalent among 3/10, 9/30, 27/90, and 36/180, we need to simplify each fraction and compare them.

Let's simplify each fraction by finding the greatest common divisor (GCD) of their numerator and denominator. Then we divide both the numerator and denominator by their GCD.

1) 3/10:
To simplify 3/10, we find the GCD of 3 and 10, which is 1. Dividing both the numerator and denominator by 1 gives us 3/10, which is already in its simplest form.

2) 9/30:
To simplify 9/30, we find the GCD of 9 and 30, which is 3. Dividing both the numerator and denominator by 3 gives us 3/10, which is the same as the first fraction. So, 9/30 is equivalent to 3/10.

3) 27/90:
To simplify 27/90, we find the GCD of 27 and 90, which is 9. Dividing both the numerator and denominator by 9 gives us 3/10, which is again the same as the first fraction. So, 27/90 is equivalent to 3/10.

4) 36/180:
To simplify 36/180, we find the GCD of 36 and 180, which is 36. Dividing both the numerator and denominator by 36 gives us 1/5. So, 36/180 simplifies to 1/5.

Comparing all the fractions, we see that 1/5 (36/180) is not equivalent to the other fractions. Therefore, 36/180 is the fraction that is not equivalent among 3/10, 9/30, 27/90, and 36/180.
