Answer 3

To evaluate the expression -25:1/2:(-4)+11•9/10:14-12,7:(-10), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right). Let's break it down step by step:

-25:1/2:(-4) (Start with division) = -25 ÷ 1/2 ÷ (-4) (Divide -25 by 1/2) = -25 ÷ 2 ÷ (-4) (Divide -25 by 1/2) = -25 ÷ 2 ÷ -4 (Divide -25 by 2) = -6.25 ÷ -4 (Divide -25 by 2) = 1.5625 (Result of the division)

Now let's continue with the rest of the expression:

+11•9/10:14-12,7:(-10) (Multiplication and division from left to right) = 11 × 9 ÷ 10 ÷ 14 - 12,7 ÷ (-10) (Multiply 11 by 9) = 99 ÷ 10 ÷ 14 - 12,7 ÷ (-10) (Divide 99 by 10) = 9.9 ÷ 14 - 12,7 ÷ (-10) (Divide 9.9 by 14) = 0.707142857 - 12,7 ÷ (-10) (Result of the division)

Now let's evaluate the remaining division:

12,7 ÷ (-10) = -1.27 (Result of the division)

Finally, let's subtract the two results:

0.707142857 - (-1.27) = 0.707142857 + 1.27 = 1.977142857

Therefore, the value of the expression -25:1/2:(-4)+11•9/10:14-12,7:(-10) is approximately 1.977142857.
