Answer 2

To solve the given expression:

81.4 - 11.5 ÷ (1 3/5 + 3 2/5)

First, let's simplify the addition within the parentheses:

1 3/5 + 3 2/5

To add mixed numbers, we need to convert them into improper fractions:

1 3/5 = (5 * 1 + 3) / 5 = 8/5 3 2/5 = (5 * 3 + 2) / 5 = 17/5

Now, we can add the fractions:

8/5 + 17/5 = (8 + 17) / 5 = 25/5 = 5

Now, the expression becomes:

81.4 - 11.5 ÷ 5

Next, let's perform the division:

11.5 ÷ 5 = 2.3

Finally, substitute the value back into the expression:

81.4 - 2.3 = 79.1

Therefore, the value of the expression is 79.1.
