18. Michael is practicing the piano. He
spends 1/2 hour practicing scales and
1/4 hour practicing the piece for his recital.
What is a common denominator for 1/2
and 1/4?
The lowest common denominator for 1/2 and 1/4 is also the lowest common multiple of 2 and 4. Since 4 is a multiple of 2, 4 itself is the lowest common multiple.
1/4 would remain, and 1/2 would be written as 2/4.
