Answer:
36
Step-by-step explanation:
"Least" means smallest.
"common" means the same.
"denominator" means the bottom number in a fraction or ratio.
This question is asking you to find the smallest number that 12 and 18 both GO INTO.
Always first check if the small number goes into the bigger number. 12 does not go evenly into 18. So it is not 18.
With small numbers like these that hopefully are familiar bc they are on the times tables you learn in elementary school, you can guess and check.
Double the 18.
It is 36. Does 12 go into 36 evenly? Yes.
We found it. 36 is the smallest number that 18 and 12 both go into.
36 is the least common denominator (LCD).
