Answer:
No they are not equivalent
Explanation:
Recall 3:5 ratio is the same as 3/8 or 5/8
ratio has to do with the sum of the two values
therefore; 3:5
3+5=8
and to know if it's equivalent we say
the first value divided by the total value gotten
which is 3/8
then apply it in the second value which is 5/8
Dividing it through you will not get 1/3
