Which fraction is equivalent to 2/5?  <br> A. 4/10 <br> B. 2/10   <br> C. 1/2   <br> D. 4/6
Lelechka [254]
Hey there James!

So, just remember, 2/5 is almost half of 1.

When it is almost half of 1, this means that it would have to be 2.5/5

This would mean that 4/10 would be your answer, because it is almost half of 1 also.

Hope this helps.
