Final answer:
The question asks to identify which of the listed ratios is not equivalent to 5/2. Through analysis, it is determined that 30/12 is not an equivalent ratio since it does not maintain the same proportion when divided. The answer is d. 30/12 is NOT an equivalent ratio to 5/2.
Step-by-step explanation:
The student has asked a question regarding ratios in Mathematics. Specifically, they need to identify which of the following is NOT an equivalent ratio to Alberto's ratio of shirts to pants, given as 5/2.
- a. 10/4
- b. 15/6
- c. 25/10
- d. 30/12
We determine equivalent ratios by multiplying or dividing both the numerator and the denominator by the same non-zero number. Given Alberto's ratio of shirts to pants is 5/2:
- a. 10/4 can be achieved by multiplying 5/2 by 2/2.
- b. 15/6 can be achieved by multiplying 5/2 by 3/3.
- c. 25/10 can be achieved by multiplying 5/2 by 5/5.
- d. 30/12 is not equivalent because dividing 30 by 12 does not give the same result as dividing 5 by 2.
Therefore, the answer is d. 30/12 is NOT an equivalent ratio to 5/2.
