Answer 1

3     1/12 - 2   3/4=  1- 9 / 12=  -1   8/12 = -  1    3 /4

Answer 2

To subtract mixed numbers like 3 1/12 and 2 3/4, you need to follow these steps:

Step 1: Convert the mixed numbers to improper fractions. Step 2: Find a common denominator. Step 3: Subtract the fractions. Step 4: Simplify the result if necessary.

Let's go through these steps:

Step 1: 3 1/12 = (3 * 12 + 1) / 12 = 37 / 12 2 3/4 = (2 * 4 + 3) / 4 = 11 / 4

Step 2: The common denominator for 12 and 4 is 12.

Step 3: 37 / 12 - 11 / 4

To subtract fractions with different denominators, you need to make sure they have the same denominator. In this case, the common denominator is 12. You can rewrite 11/4 with a denominator of 12:

11 / 4 = (11 * 3) / (4 * 3) = 33 / 12

Now the subtraction becomes:

37 / 12 - 33 / 12 = (37 - 33) / 12 = 4 / 12

Step 4: The fraction 4/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:

4 / 12 = (4 ÷ 4) / (12 ÷ 4) = 1 / 3

So, 3 1/12 - 2 3/4 = 1/3.

Therefore, the result of subtracting 3 1/12 - 2 3/4 is 1/3.
