Answer 2

To simplify the expression (2 + 4 + 1 7/5) × 11 3/2, 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).

First, let's simplify the expression inside the parentheses:

2 + 4 + 1 7/5 = 6 + 1 7/5

Now, let's convert the mixed number 1 7/5 into an improper fraction:

1 7/5 = (5 * 1 + 7) / 5 = 12/5

So, the expression inside the parentheses simplifies to:

6 + 12/5

To add these two fractions, you need a common denominator, which is 5:

6 + 12/5 = (6 * 5/5) + 12/5 = 30/5 + 12/5 = 42/5

Now, the expression inside the parentheses is 42/5. Next, let's calculate the expression as a whole:

(42/5) × 11 3/2

Now, multiply the two fractions:

(42/5) × (11 3/2)

To multiply mixed numbers, first convert them to improper fractions:

11 3/2 = (2 * 11 + 3) / 2 = 25/2

Now, multiply the fractions:

(42/5) × (25/2)

To multiply fractions, simply multiply the numerators together and the denominators together:

(42 * 25) / (5 * 2)

Now, calculate the numerator and denominator:

Numerator: 42 * 25 = 1050 Denominator: 5 * 2 = 10

So, the final result is:

1050/10 = 105/1 = 105
