Subtract 9 3/8 from 12 1/6

2 19/24

Step-by-step explanation:

First, you need to change the denominators so they are the same. You need a denominator that is the same and can by multiplied both 8 and 6. I will use 24 as the denominator. Now, find what equals 24 when multiplied by 8. 8 x what equals 24? The correct answer is 3. However, whatever you do to the denominator, you have to do to the numerator. Multiply 3 by the numerator 3 to get 9. So, your first fraction is 9/24. Next, 6 times what equals 24? The correct answer is 4. Once again, whatever you do to the denominator, you have to do to the numerator. 1 times 4 equals 4. So, your second fraction is 4/24. Now, you can subtract. 4/24 - 9/24. Since you can't do this, you need to borrow from the 12. The 12 changes into 11 and 4/24 changes 28/24, because 4/24 + 24/24 equals 28/24. Now, 28/24 -9/24= 19/24. Now, you can subtract the whole numbers. 11-9 equals 2, so your final answer is 2 19/24.
