Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this case, you don't have parentheses or exponents, so you can perform multiplication and division from left to right and then addition.

Let's break it down step by step:

1. First, simplify the multiplication and division from left to right:

   5 8/9 ÷ 1 17/36 + 1 1/4 × 5/21

   Start with the division:

   (5 8/9) ÷ (1 17/36) + (1 1/4) × (5/21)

2. Now, let's perform the division:

   To divide mixed numbers, convert them to improper fractions and then divide:

   (53/9) ÷ (53/36) + (5/4) × (5/21)

3. Now that we have converted the mixed numbers to improper fractions, let's divide and multiply:

   (53/9) ÷ (53/36) + (5/4) × (5/21)

   Now, we'll perform the division and multiplication:

   (53/9) ÷ (53/36) = (53/9) × (36/53) = 36/9 = 4

   (5/4) × (5/21) = (25/84)

4. Now, we can add the results:

   4 + 25/84

5. To add these fractions, you need a common denominator, which is 84 in this case:

   (4 * 84/84) + (25/84)

6. Now, you can add the fractions:

   (336/84) + (25/84)

7. Add the numerators:

   336 + 25 = 361

8. The final fraction is 361/84.

So, the simplified result of the expression is 361/84.
