Answer 2

To solve this expression, you should follow the order of operations, which is typically referred to as PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). In this case, you have multiplication and division, so you should perform them from left to right. Here's the calculation step by step:

1. Start with the first multiplication: 3 7/9 * 1 1/17

   To multiply mixed numbers, convert them to improper fractions: 3 7/9 = (3 * 9 + 7)/9 = 34/9 1 1/17 = (1 * 17 + 1)/17 = 18/17

   Now, multiply the fractions: (34/9) * (18/17)

   Multiply the numerators and denominators: (34 * 18) / (9 * 17) = 612 / 153 = 4

2. Move on to the next multiplication: 4 * 9 1/7

   Convert the mixed number to an improper fraction: 9 1/7 = (9 * 7 + 1)/7 = 64/7

   Now, multiply the fractions: 4 * (64/7)

   Multiply the whole number by the numerator of the fraction: (4 * 64) / 7 = 256/7

3. Proceed to the next multiplication: (256/7) * (3/4)

   Multiply the fractions: (256/7) * (3/4)

   Multiply the numerators and denominators: (256 * 3) / (7 * 4) = 768/28

4. Finally, move on to the last multiplication: (768/28) * 5 1/2

   Convert the mixed number to an improper fraction: 5 1/2 = (5 * 2 + 1)/2 = 11/2

   Now, multiply the fractions: (768/28) * (11/2)

   Multiply the numerators and denominators: (768 * 11) / (28 * 2) = 8448/56

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 8:

(8448/8) / (56/8) = 1056/7

So, the final result is 1056/7 or 151 5/7.
