6*45=270 is the first step you should do to get the answer you are looking for. The next thing I would do is go to all the answers to see which one comes out the same way. The first one comes to be 246, the next one is 54, the next is 270 and the last one is 220. 6*40+6*5 is the correct answer.
660 would be the nearest ten. you round up because the final number is with 5 or greater. if the final number was 4 or less, you would round down. I hope this helped you
