To calculate the expression "15 8/10 - 9 9/10 + 6 3/10," we need to perform the operations in the correct order, considering both whole numbers and fractions. Let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions. 15 8/10 = 15 + 8/10 = 150/10 + 8/10 = 158/10 9 9/10 = 9 + 9/10 = 90/10 + 9/10 = 99/10 6 3/10 = 6 + 3/10 = 60/10 + 3/10 = 63/10

Step 2: Perform the addition and subtraction operations. 158/10 - 99/10 + 63/10

Step 3: Simplify the fractions with a common denominator (10). (158 - 99 + 63)/10 = 122/10

Step 4: Simplify the fraction, if possible. 122/10 = 61/5

Therefore, the expression "15 8/10 - 9 9/10 + 6 3/10" simplifies to 61/5.
