Answer 2

To solve the given expression, let's break it down step by step:

1. Simplify the expression within the parentheses: (-8/29) • (15/14) - (11/40) - Multiply the numerators together: (-8) • (15) = -120 - Multiply the denominators together: (29) • (14) = 406 - The expression within the parentheses simplifies to -120/406.

2. Divide -120/406 by (-7/8): - To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. - The reciprocal of (-7/8) is (-8/7). - Multiply -120/406 by (-8/7): - Multiply the numerators together: (-120) • (-8) = 960 - Multiply the denominators together: (406) • (7) = 2842 - The result of the division is 960/2842.

Therefore, the simplified value of the expression -8/29 • 15/14 - 11/40 : (-7/8) is 960/2842.

Please note that the above solution is based on the given expression and the mathematical operations involved.
