There are 12 counters in 1/7 of a set. How many counters are in the whole set
(1/7)x = 12
x = 7*12 = 81

There are 10 counters in a set. How many counters are in 1/2 of a set?
x = 10
(1/2)x = (1/2)(10) = ...

If 2/3 of a set is 16, what is 1/4 of a set?
(2/3)x = 16
2x = 48
x = 24
then (1/4)x = (1/4)(24) = ....

If 3/4 of a set is 12, what is 1/8 of a set?
(3/4)x = 12
x = 12(4/3) = 16
then (1/8)x = (1/8)(16) = ...
