Answer:
20.25
Step-by-step explanation:
Step 1: Turn 32 3/4 into a improper fraction.
To do this, multiply the whole number (32) by the denominator (4) to get the answer of 128. Then add 128 to the numerator (3), to get 131. Keep the denominator the same.
The outcome is 131/4
Step 2: Turn 12 1/2 into a improper fraction.
Do the same thing as with 34 3/4. Multiply 12 by 2, get 24 and add 24 to 1.
The outcome is 25/2
Step 3: Find the common denominator. In this case, the common denominator is 4, so multiply 25, and 2 by 2 to get 4.
Step 4: Subtract!
131/4 - 50/4 = 81/4
Step 5: Turn 81/4 into a decimal.
