You take 50 times .082 which is 8.2% in decimal form to get 4.1
456÷12= 38

Answer: 14
Step-by-step explanation:

in case you wonder why we used 105 as LCD,
21 = 3 * 7
15 = 3 * 5
the "3" is common to both denominators, so we "use it once" and our LCD is then 3 * 7 * 5.
I think the answer would be J?
