Quizplus · Accepted Answer

Step 1: Convert 4 ³/₅ and 9 ³/₄ to improper fractions to make subtraction easier. Use the rule a ^b/_c = ac + ^b/_c 11ec0fda_98cb_24f5_a67f_4b196af8153b_NR0004_00 Step 2: Simplify: 11ec0fda_98cb_24f6_a67f_132137e286a2_NR0004_00 Step 3: 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 5: 5, 10, 15, 20… Multiples of 4: 4, 8, 12, 16, 20… Therefore, the LCD is 20. Method 2: Prime Factors. The LCD will be the product of the largest multiple of each prime that appears on at least one list. Prime factors of 5: 5 Prime factors of 4: 2, 2 Therefore, the LCD is 2 × 2 x 5 = 20. Step 4: Make the denominators the same as the LCD. 11ec0fda_98cb_24f7_a67f_a1c9321908ec_NR0004_00 Step 5: Simplify. The denominators are now the same. 11ec0fda_98cb_24f8_a67f_6d9b74463211_NR0004_00 Step 6: Join the denominators. 11ec0fda_98cb_24f9_a67f_535afc246cd7_NR0004_00 Step 7: Simplify. 11ec0fda_98cb_24fa_a67f_1f365dc42a03_NR0004_00 Step 8: Convert to mixed number. 11ec0fda_98cb_24fb_a67f_71e1bf0b5b72_NR0004_00 Answer: 14 ⁷/₂₀
