Answer 2

15*((42-40-25)/75)=15*(-23)/75=-23/5=-4,6

Answer 3

To evaluate the expression 15 * (14/25 - 8/15 - 1/3), we can simplify it step by step:

Step 1: Simplify the fractions within parentheses. 14/25 - 8/15 - 1/3 = (14/25) * (3/3) - (8/15) * (5/5) - (1/3) * (25/25) = 42/75 - 40/75 - 25/75 = (42 - 40 - 25) / 75 = -23/75

Step 2: Substitute the simplified fraction back into the expression. 15 * (-23/75) = -345/75

Step 3: Simplify the resulting fraction. -345/75 = -23/5

Therefore, 15 * (14/25 - 8/15 - 1/3) equals -23/5.
