Here are the solutions to the problems: Problem 1: Subtract: 12(4)/(7) - 9(1)/(7) Step 1: Subtract the whole number parts. 12 - 9 = 3 Step 2: Subtract the fractional parts. Since the denominators are the same, subtract the numerators. (4)/(7) - (1)/(7) = (4-1)/(7) = (3)/(7) Step 3: Combine the whole number and fractional parts to form the mixed number. 3 + (3)/(7) = 3(3)/(7) The result is 3(3)/(7). Problem 2: Simplify: 49 + 64 ÷ 8 × 3 - 10 Step 1: Perform division first, as it appears before multiplication from left to right. 49 + (64 ÷ 8) × 3 - 10 49 + 8 × 3 - 10 Step 2: Perform multiplication. 49 + (8 × 3) - 10 49 + 24 - 10 Step 3: Perform addition from left to right. (49 + 24) - 10 73 - 10 Step 4: Perform subtraction. 63 The simplified value is 63.
