Answer: So think about it this way. 20 goes into 200 ten times, right?
After that, you have 75 left. 20 goes into 60 3 times. After that, you have 15 left.
But wait, 20 can't go into 15 as a whole. So you have to make that a fraction.
15/20. That fraction can be simplified! Divide each part by five. The you get 3/4.
So add up the times you put 20 in. First it was 10 to get to 200, then it was 3 to get to 60. Then it was 3/4 to get to 15.
Now you have 13 3/4
