Answer:
30 is a common denominator. 5/30, 18/30
Step-by-step explanation:
6*1=6, 6*2=12, 6*3=18, 6*4=24, 6*5=30
5*1=5, 5*2=10, 5*3=15, 5*4=20 5*5=25, 5*6=30
after multiplying you see they both will eventually equal 30.
then multiply the numerator for how ever many times you multiplied the denominator
1*5=5
3*6=18
5/30 and 18/30
