Answer:
In order to
add 1/4 and 2/3 it is necessary to rewrite the fractions so
that the bottom numbers (the denominators) are the same. In this
case, since 12 is the smallest number which is 4 and 3 divide into,
the fractions can be rewritten as twelfths. 12 is the common denominator
1/4 = 3/12 and
2/3 = 8/12
Then 1/4 +
2/3 = 3/12 + 8/12 = 11/12
