Answer 2

To calculate the expression 8/5 * 3/4 + 11/8, 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 expression, you have multiplication and addition:

1. First, calculate the multiplication: (8/5) * (3/4) = (8 * 3) / (5 * 4) = 24/20 = 6/5.

2. Now, you can add the result of the multiplication to 11/8: 6/5 + 11/8.

To add these fractions, you need to find a common denominator, which in this case is 40. So, you need to rewrite both fractions with a denominator of 40:

• For 6/5, you can multiply both the numerator and denominator by 8 to get (6 * 8)/(5 * 8) = 48/40.
• For 11/8, you can multiply both the numerator and denominator by 5 to get (11 * 5)/(8 * 5) = 55/40.

Now, the expression becomes:

(48/40) + (55/40).

3. Add the fractions with the common denominator: (48/40) + (55/40) = (48 + 55)/40 = 103/40.

So, the final result is 103/40.
