Question

Is 3/12 equivalent to 1/4?

Answer 1

No,
12 divided by 4 equals 3
Since you can't do 3 divided by four, it's not equivalent.

Answer 2

for this question you should know that you can multiply both number in 1/4 by 3 and you will have:
1*3 / 4*3 = 3/12
so the answer is yes they are equivalent :)))
