Explanation:
to compare wd need to simplify and to simplify divide both numbers with biggest common divider
3/4 is equivalent to 12/16 because if we simplify it with 4 ➡ 3/4
25/35 and 10/14 is also equivalent when simplified it will be 5/7 and 5/7
12/17 and 10/15 are not equivalent because 17 cannot be simplified
