Calculating the Expressions

Let's calculate the value of the given expressions step by step.

1. Expression 1: (4/5 - 11/15) * 5/11 First, let's calculate the value inside the parentheses: - 4/5 - 11/15 = (12/15 - 11/15) = 1/15 Then, multiply the result by 5/11: - (1/15) * (5/11) = 5/165

Therefore, the value of the first expression is 5/165.

2. Expression 2: 7/88 * (8/21 + 8/7) First, let's simplify the expression inside the parentheses: - 8/21 + 8/7 = (8/21 + 24/21) = 32/21 Then, multiply the result by 7/88: - (32/21) * (7/88) = 224/1848 = 14/99

Therefore, the value of the second expression is 14/99.

3. Expression 3: 3/7 * (1/4 + 7/12) First, let's simplify the expression inside the parentheses: - 1/4 + 7/12 = (3/12 + 7/12) = 10/12 = 5/6 Then, multiply the result by 3/7: - (5/6) * (3/7) = 15/42 = 5/14

Therefore, the value of the third expression is 5/14.

So, the values of the given expressions are: 1. (4/5 - 11/15) * 5/11 = 5/165 2. 7/88 * (8/21 + 8/7) = 14/99 3. 3/7 * (1/4 + 7/12) = 5/14
