Hello there!
Equivalent is something that is equal to another thing. Non-equivalent is obviously something that is not equation.
They give 2 fractions. In order to find out if they are equal or not, we must turn both of them into decimal.
How do you do that?
Well, just take your calculator then take the number on top (numerator) then divide by the number at the bottom (denominator).
3/5 = 0.6
7/23 = 0.30
Thus,
The fractions are Nonequivalent!
The correct answer is the first option.
I hope this answer is clear enough to understand. Let me know if you have any misunderstanding!
As always, I'm glad to be your helper!
