Question

When Using Fraction Strips, How Do You Know That Two Fractions Are Not Equivalent?

Answer 1

Well, line them up and make sure they end the same. Then, see if they meet the same point. If it's something like 32/100 and 23/50, it might be best to use a ruler. Also, the slightest bit of aprt will mean they aren't equivalent

Answer 2

If the stripes are not lined up equally then they are not equivalent. 

hope this helps :D
