Answer :
The lowest common denominator is the smallest number that 10 and 15 can get into.
first you have to list the first 10 multiples of 10
10,20,30,40,50,60,70,80,90,100
and then the first ten multiples of 15
15, 30, 45, 60, 75, 90, 105, 120, 135
The smallest number that both of them have is 30 so that's the Lowest Common Denominator
The least common denominator is the smallest number that 10 and 15 can get into.
List the multiples:
10:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100
15:
15, 30, 45, 60, 75, 90, 105, 120, 135
The smallest number that both of them have is 30, so that's the LCD.
