Answer:
no they are not equivalent
Explanation:
if you look at 1/2 you can already infer that in decimal form it is .50 (so its half of 100, sorry if that doesn't make sense!), and if we look at 4/5 we can tell that in decimal form it is .80 because 100÷5 =80. so therefore, 4/5 and 1/2 are NOT equivalent.
