Answer:
No, they are not equivalent fractions.
Explanation:
Simplify 42/70.
42/70
Divide by 7.
42/70 = 6/10
Now, divide by 2.
6/10 = 3/5.
7/12 cannot be further simplified as the numerator & denominator have no common factor between them.
3/5 is not equivalent to 7/12.
3/5 = 0.6
7/12 = 0.58
Hence, they are not equivalent fractions.
