Answer 3

To solve the given expression, follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) to simplify step by step:

Expression: 3 - 15/26 * 1 1/6 * 2 2/19

Step 1: Convert mixed numbers to improper fractions. 1 1/6 = (6 * 1 + 1) / 6 = 7/6 2 2/19 = (19 * 2 + 2) / 19 = 40/19

Step 2: Perform multiplication and division from left to right. 15/26 * 7/6 = (15 * 7) / (26 * 6) = 105 / 156 1 - 105/156 * 40/19

Step 3: Multiply the fractions. 105/156 * 40/19 = (105 * 40) / (156 * 19) = 4200 / 2964

Step 4: Simplify the fraction. 4200 / 2964 = 1400 / 988 = 350 / 247

Step 5: Subtract the result from 1. 1 - 350/247

Step 6: Find a common denominator for the subtraction. The common denominator for 247 and 1 is 247.

Step 7: Perform subtraction. 247/247 - 350/247 = (247 - 350) / 247 = -103 / 247

So, the simplified result of the expression is -103/247.
