This is a simple subtraction problem, but since you are in Elementary School, I will help you out.
Subtract $4,190.67 by $3,655.11 (remember, the bigger number should come first)
4,190.67 <span>-3,655.11 </span> ...56
When a small number is on top of a bigger number, borrow 1 number from the number next to it (in this case, 0 is smaller than 5, so you must borrow 1 number from 9, making it to 8), then add the small number by 10 (0+0=10) <span>Then we continue...
We search for red balls (neither yellow or black). There are 6 red balls among all 18 balls. Selecting one ball, there is a chance 6/18 that we pull out a red one. 6/18 is the same as 1/3.
