Answer 3

To simplify the expression 1:1,6(17/4:17):2/3+(7/2-1/4)×20/13, follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), Addition and Subtraction (left-to-right).

First, let's break down the expression step by step:

1. Start with the innermost parentheses: 17/4:17 = (17/4) ÷ 17 = 17/4 ÷ 17 = 17/4 * 1/17 = (17 * 1) / (4 * 17) = 17/68 = 1/4

2. Now, substitute this result back into the expression: 1:1,6(1/4):2/3 + (7/2 - 1/4) × 20/13

3. Continue evaluating the expression:

   1:1,6(1/4):2/3 + (7/2 - 1/4) × 20/13

   1:1,6(1/4):2/3 + (14/2 - 1/4) × 20/13

   1:1,6(1/4):2/3 + (7 - 1/4) × 20/13

4. Now, evaluate the expressions from left to right:

   1:1,6(1/4):2/3 = 1,6(1/4):2/3 = 1.6 * (1/4) / (2/3)

   To divide by a fraction, you multiply by its reciprocal: 1.6 * (1/4) * (3/2) = 0.6 * 3/2 = 0.9

   So, the expression becomes:

   0.9 + (7 - 1/4) × 20/13

5. Continue evaluating:

   0.9 + (28/4 - 1/4) × 20/13

   0.9 + (27/4) × 20/13

6. Multiply the fractions:

   0.9 + (27/4) * (20/13)

   (0.9 * 13) + (27/4 * 20)

   11.7 + (27/4 * 20)

7. Multiply the whole number by the fraction:

   11.7 + (27/4 * 20/1)

   11.7 + (27 * 20) / (4 * 1)

   11.7 + 540/4

8. Add the fractions:

   11.7 + 135

9. Finally, add the decimals:

   11.7 + 135 = 146.7

So, the simplified value of the expression is 146.7.
