Bonus Knowledge
To find equivalent fractions using a common denominator, we first identify the least common multiple (LCM) of the denominators.
For
and
, the LCM of 2 and 8 is 8. Thus, we convert
to
(by multiplying both the numerator and denominator by 4), making the equivalent fractions
and
.
For
and
, the LCM of 9 and 3 is 9. We keep
as is and convert
to
(by multiplying by 3). The equivalent fractions are now
and
