Let me know if this helps :)
To be able to quickly solve this, we can temporarily make 5.47 into 547
Now, we can divide 547 by 12.
Now, we can round up from 45.5 to get 46.
However, we originally moved our decimal 2 places over, so now we must move it 2 places again.
46 ⇒ 0.46
The correct answer is $0.46
The scale 1:35 indicates that for every 1 meter on the scale model, there are really 35 meters in real life.
So if the scale model is 6.6 meters, you would do 35 * 6.6 to find the length in real life, which is 231 meters.
The answer is 231 meters.
