Answer:
13,00 + 5,000 - 3,000= 15,000
okie
Step-by-step explanation:
The answer is the first option
12,24 etc
4 and 6 both go into 12 evenly
4*3 = 12
6*2 = 12
12 is the least common denominator
We could also use 24
4*6 = 24
It is a common denominator, but not the least common denominator
We can use any multiple of 12
