Answer:
45.
Step-by-step explanation:
Find the LCM (Least Common Multiple):
- We can use a factorization tree or make a list of values.
Lets list out the multiples of 5 and 9 (Denominators)
5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50.
9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90
45 is the least common multiple.
<u>Multiply the denominator to get to 45</u><u>,</u><u> </u><u>same</u><u> </u><u>applies</u><u> </u><u>for</u><u> </u><u>numerator</u><u>:</u>
45 is the least common multiple that you can use for your denominators.
