Read the problem. Explain why A cannot be the correct answer choice. Then choose the correct answer.
Which fraction is not equivalent to the others?
A 2/8
B 1/4
C 6/18
D 3/12
6/18
could you explain how you got 6/18
To determine which fraction is not equivalent to the others, we need to identify the fractions that can be simplified to an equivalent fraction. Let's analyze each answer choice.
A) 2/8: This fraction can be simplified because both the numerator and denominator share a common factor of 2. Simplifying 2/8 by dividing both the numerator and denominator by 2 gives us 1/4.
B) 1/4: This fraction is already in its simplest form. There are no common factors between the numerator and denominator that can be divided.
C) 6/18: To check if this fraction can be simplified, we need to find the greatest common factor (GCF) of 6 and 18. The GCF of 6 and 18 is 6. Dividing both the numerator and denominator of 6/18 by 6 gives us 1/3.
D) 3/12: This fraction can also be simplified. The GCF of 3 and 12 is 3. Dividing both the numerator and denominator of 3/12 by 3 gives us 1/4.
From the analysis above, we can conclude that option A (2/8) can be simplified to 1/4, making it equivalent to option B (1/4). This means that option A and B are equivalent fractions.
Therefore, the correct answer is option C (6/18) because it simplifies to 1/3, which is not equivalent to options A, B, and D.
