here is a neat trick

suppose you want to see which is larger

6/11 or 13/27

write them side by side

6/11 13/17

cross multiply , topleft to bottom right first, the the other way, write them side by side

102 143

place the correct > or < symbol between them

102 < 143

so 6/11 < 13/17

Of course since you probably have a calculator handy anyway, why not just change the fraction to a decimal, then decide, How easy is that?
