Here are the solutions for the remaining problems: 6. Step 1: Find a common denominator for (7)/(10), (15)/(30), and (3)/(20). The least common multiple of 10, 30, and 20 is 60. (7)/(10) - (15)/(30) + (3)/(20) = (7 × 6)/(10 × 6) - (15 × 2)/(30 × 2) + (3 × 3)/(20 × 3) Step 2: Perform the operations. = (42)/(60) - (30)/(60) + (9)/(60) = (42 - 30 + 9)/(60) = (12 + 9)/(60) = (21)/(60) Step 3: Simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 3. = (21 ÷ 3)/(60 ÷ 3) = (7)/(20) The final answer is (7)/(20). 7. Step 1: Find a common denominator for (5)/(14), (3)/(28), and (3)/(4). The least common multiple of 14, 28, and 4 is 28. (5)/(14) - (3)/(28) + (3)/(4) = (5 × 2)/(14 × 2) - (3)/(28) + (3 × 7)/(4 × 7) Step 2: Perform the operations. = (10)/(28) - (3)/(28) + (21)/(28) = (10 - 3 + 21)/(28) = (7 + 21)/(28) = (28)/(28) Step 3: Simplify the fraction. = 1 The final answer is 1.
