Answer:
B
Explanation:
I am not a 100% sure but I'll go with B because 3x10 is equal to 30 and if you times 5 by 10 it would be 50. Hope it helps sorry if it doesn't.
Comment
Two answers are correct. A and D.
Since the question says "equivalent fractions" I would choose A, but if it allows 2 answers then choose D as well.
