Step 1: Find the Least Common Denominator (LCD). There are two ways we can do this: Method 1: Find the first common multiple. List out all multiples of each denominator and find the first common one. Multiples of 14 : 14, 28, … Multiples of 7 : 7, 14, 21, 28, … Multiples of 28 : 28, … Therefore, the LCD is 28. Method 2: Prime Factors. List all prime factors of each denominator and find the union of these primes. Prime factors of 14 : 2, 7 Prime factors of 7 : 7 Prime factors of 28 : 2, 2, 7 Therefore, the LCD is 2 × 2 × 7 = 28. LCD = 28 Step 2: Make the denominators the same as the LCD. 11ec0fda_98d0_0794_a67f_993f14bdac2f_NR0004_00 Step 3: Simplify. The denominators are now the same. 11ec0fda_98d0_2ea5_a67f_0fb91b9cc8f2_NR0004_00 Step 4: Join the denominators. 11ec0fda_98d0_2ea6_a67f_a5b7d18c161c_NR0004_00 Step 5: Simplify. 11ec0fda_98d0_2ea7_a67f_7787fb6d462c_NR0004_00 Step 6: Convert to a mixed number. 11ec0fda_98d0_2ea8_a67f_012380328609_NR0004_00 Answer: 1 ¹⁵⁄₂₈
