Answer:
C. 12/15
Step-by-step explanation:
As it is mentioned above, the below text is the explanation, if you were here for the answer, it is above.
The question is asking which ratio is not equivalent. To simplify a ratio, divide all of the numbers in the ratio by the same number until they cannot be divided anymore.
So when we look at A. we see that you can not simplify 2/3 anymore. Hence:
A (simplified version): 2/3
When we look at B. we see that the ratio, or fraction, is 6/9. The numerator, or the top number, is 6, while the denominator (the number on the bottom), is 9. The GCF (The greatest common factor, or GCF, is a term used to describe the biggest number that can divide evenly into two or more numbers. Sometimes, this is also referred to as the greatest common divisor, GCD, or highest common factor, or HCF. A factor is a smaller number that can divide evenly into that number) of 6 and 9 is 3. So we divide the numerator and the denominator (both) by 3 to get to 2/3. Hence:
B (simplified version): 2/3
Now, when we look at C. we see that the ratio is 12/15. What is the GCF of 12/15? The GCF is 3. So we divide the numerator and the denominator by 3 to get:
C (simplified version): 4/5
Moving on to D. Let's make it quick. The ratio is 18/27. The GCF is 9. So we divide the numerator and the denominator by 9 to get::
D (simplified version): 2/3
If:
A (simplified version): 2/3
B (simplified version): 2/3
C (simplified version): 4/5
D (simplified version): 2/3
The one fraction that is not equivalent? I'll let you figure that out for yourself!
