Answer 2

To simplify the given expression, let's perform the calculations step by step:

Step 1: Simplify the fractions. 1/3 - 1/12 = (4/12) - (1/12) = 3/12 = 1/4 1/7 - 1/5 = (5/35) - (7/35) = -2/35

Step 2: Substitute the simplified fractions back into the expression. 23 * (1/4) - 35 * (-2/35)

Step 3: Perform the multiplications. 23 * (1/4) = 23/4 35 * (-2/35) = -2

Step 4: Simplify the final expression. 23/4 - 2

To add or subtract fractions, we need a common denominator. In this case, the common denominator is 4. (23 - 8) / 4 = 15/4

Therefore, the simplified expression is 15/4.
