Answer 3

To solve the expression (20 1/2 + 12 3/5) * (1/10), we need to convert the mixed numbers into improper fractions and then perform the calculations. Let's break down the steps:

Step 1: Convert mixed numbers to improper fractions: 20 1/2 = (20 * 2 + 1) / 2 = 41/2 12 3/5 = (12 * 5 + 3) / 5 = 63/5

Step 2: Add the improper fractions: (41/2 + 63/5)

Step 3: Find the common denominator: To add fractions, we need a common denominator. The least common multiple (LCM) of 2 and 5 is 10. Therefore, we'll convert the fractions to have a denominator of 10.

41/2 = (41/2) * (5/5) = 205/10 63/5 = (63/5) * (2/2) = 126/10

Step 4: Add the fractions: 205/10 + 126/10 = (205 + 126) / 10 = 331/10

Step 5: Multiply the fraction by 1/10: (331/10) * (1/10) = 331/100

Therefore, the result of the expression (20 1/2 + 12 3/5) * (1/10) is 331/100.
