220, you just round it, it easy when you learn it
First, I would create a number line that includes the number -4 to 4, with 1/4 notches (3 notches between each number).
For 3, I would count 3 numbers to the right from zero.
For 2.25, I would count 2 numbers from zero, plus one additional notch to the right. Remember that each notch represents 1/4, or 0.25.
For the opposite of 4, I would count 4 to the left to -4. The opposite of 4 is -4.
For -(-1 1/2), I would remember that this number is actually 1 1/2, since a negative times a negative number is positive. I would count one number to the right of zero, plus two notches.
V= 1/3AH, thats the formula
