If you cross multiply you will get the same answer from equivalent fractions,

Explanation:

You can check in one step whether fractions are equivalent or not.

Consider #2/3 and 8/12#

If they are equivalent fractions, when you cross multiply you will get the same product each time:

#color(blue)(2)/color(red)(3) and color(red)(8)/color(blue)(12)#

#color(blue)(2xx12) and color(red)(3xx8)#

#color(blue)(24) = color(red)(24)#

Therefore the fractions are equivalent.

Consider:

#5/9 and 6/11" "larr# both are slightly more than #1/2#

#55 !=54#

The fractions are not equivalent.
