Answer :

1/2  1/3  1/4  1/8 1/12

the bigger the denominator the smaller the portion. Think of it like a pizza you can have a pizza cut into 8 slices or 10 slices the pizza will still be the same size but there will be smaller pieces if it is divided into ten rather than eight
1/2 , 1/3, 1/4 ,1/8,1/12 Just remember if all the numerators are one then the one with the smallest denominator is the greatest fraction.
