To find the number that makes the equation -8 1/2 + ? = -5 1/2 true, we need to solve for the missing number (?).
To begin, we can subtract -8 1/2 from both sides of the equation. This will cancel out the -8 1/2 on the left side, leaving us with just the missing number (?). On the right side, we have -5 1/2 - -8 1/2.
When subtracting fractions, we need to find a common denominator. In this case, the denominators are already the same (2). So we can subtract the numerators directly.
-5 1/2 - -8 1/2 is equivalent to -5 - (-8) = -5 + 8 = 3.
Therefore, the missing number (?) is 3.
So, -8 1/2 + 3 = -5 1/2 is true.Answer:
