To find the answer to the expression 3 1/4 - 1 1/2, you can follow these steps:

Step 1: Convert the mixed numbers to improper fractions.
3 1/4 is equivalent to (4 * 3 + 1) / 4, which simplifies to 13/4.
1 1/2 is equivalent to (2 * 1 + 1) / 2, which simplifies to 3/2.

Step 2: Subtract the fractions.
To subtract fractions, you need a common denominator. In this case, the least common multiple (LCM) of 4 and 2 is 4.

So, multiply the numerator and denominator of the first fraction (13/4) by 2 to get 26/8.
Multiply the numerator and denominator of the second fraction (3/2) by 4 to get 12/8.

Now you have 26/8 - 12/8.

Step 3: Subtract the numerators and keep the denominator the same.
26/8 - 12/8 = (26 - 12) / 8 = 14/8.

Step 4: Simplify the fraction, if possible.
The fraction 14/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2. Doing this, you get 7/4.

So, the answer to the expression 3 1/4 - 1 1/2 is 7/4, which can also be expressed as 1 3/4.

Therefore, your answer of 1 3/4 is correct.
