Answer 3

To solve the expression (2.5 + 1 2/3) * (4 1/3 - 1 5/6), let's break it down step by step.

First, let's simplify the addition and subtraction within the parentheses: 2.5 + 1 2/3 = 2.5 + 5/3 We need to convert the mixed number 1 2/3 to an improper fraction: 1 2/3 = (1 * 3 + 2) / 3 = 5/3 Now we can add: 2.5 + 5/3 = 7/2 + 5/3

Next, let's simplify the subtraction: 4 1/3 - 1 5/6 = (4 * 3 + 1) / 3 - (1 * 6 + 5) / 6 = 13/3 - 11/6

Now we can substitute the simplified expressions back into the original expression and perform the multiplication: (7/2 + 5/3) * (13/3 - 11/6)

To multiply fractions, we multiply the numerators together and the denominators together: [(7 * 3) + (5 * 2)] / (2 * 3) * [(13 * 6) - (11 * 3)] / (3 * 6)

Simplifying further: (21 + 10) / 6 * (78 - 33) / 18 31/6 * 45/18

To multiply fractions, we multiply the numerators together and the denominators together: (31 * 45) / (6 * 18) = 1395/108

Therefore, the result of the expression (2.5 + 1 2/3) * (4 1/3 - 1 5/6) is 1395/108.
