7.75-2.75=5

Answer 2

To solve the given expression, follow these steps:

Step 1: Convert the mixed number to an improper fraction. -3 1/4 = -3 + 1/4 = -12/4 + 1/4 = -11/4

Step 2: Subtract the second number from the first. -11/4 - 2.75

Step 3: Convert the second number to an improper fraction. 2.75 = 2 + 0.75 = 2 + 75/100 = 2 + 3/4 = 8/4 + 3/4 = 11/4

Now, the expression becomes: -11/4 - 11/4

Step 4: Subtract the fractions. (-11/4) - (11/4) = -22/4

Step 5: Simplify the result, if possible. -22/4 = -11/2

So, the final result of the expression -3 1/4 - 2.75 is -11/2.
