Answer:
1 5/12
Step-by-step explanation:
First, take 4 and subtract the 3. This leaves you with 1.
Second, take 2/3 and 1/4 and find the least common denominator. In this case, the LCD would be 12.
Now, take 2/3 and and multiply it by 4. You get 8/12. Take 1/4 and multiply it by 3. You get 3/12.
Now that both numbers have a common denominator, you can subtract the numerators. So, 8/12 - 3/12 leaves you with 5/12. Now you have your answer of 1 5/12.
