we need to find out the unit ratio for one of the 16 cups

5.6/16=0.35

now we need to do the same thing with the others and figure out which ones have the same unit ratio

0.7/2=0.35 yes
1.6/4=0.4   no
2.8/8=0.35 yes
3/10=0.3  no
6.3/18=0.35 yes
7/20=  0.35 yes

so, the 2,8,18, and 20 are the same
