Answer:
Explanation:
To subtract -8 1/4 from -3 1/2, we need to convert both mixed numbers to improper fractions:
-3 1/2 = -7/2
-8 1/4 = -33/4
Now we can rewrite the expression as:
-7/2 - (-33/4)
To subtract a negative number, we can change it to addition and flip its sign:
-7/2 + 33/4
Now we need to find a common denominator, which is 4:
-7/2 * 2/2 + 33/4
Simplifying the numerator, we get:
-14/4 + 33/4
Now we can combine the like terms:
19/4
Therefore, -3 1/2 - (-8 1/4) = 19/4.
