Hi Dragon Slayer,
Let's look at this
First, you change the decimal 0.04 into 4/1,000. Wrong
Then, you change 12 into a fraction. 12=12/1 Correct
After that, do the reciprocal for 4/1,000. 4/1,000=1,000/4 No, you don't do that.
Then, you multiply 12/1 by 1,000/4. No
So, the answer is 1/300. Sorry but 12/1*1000/4=3000
Hope it helps, Melody. Nope didn't help
