Answer 3

To solve this arithmetic expression, you'll need to find a common denominator for the fractions and then perform the calculations. Here are the steps:

Step 1: Find a common denominator for 8, 7, and 2. The least common multiple (LCM) of these numbers is 56.

Step 2: Rewrite each fraction with the common denominator of 56:

• 7/8 becomes (7/8) * (7/7) = 49/56
• 4/7 becomes (4/7) * (8/8) = 32/56
• 1/2 becomes (1/2) * (28/28) = 14/56

Step 3: Now that all the fractions have the same denominator, you can add and subtract them:

49/56 - 32/56 + 14/56

Step 4: Perform the arithmetic:

49/56 - 32/56 + 14/56 = (49 - 32 + 14)/56 = 31/56

So, 7/8 - 4/7 + 1/2 = 31/56.
