69/4:29/20
345/29

Answer 2

To solve the expression 17,25:(4,25-2 7/9* 3 3/5, you need to follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break down the expression step by step:

1. Start with the operations inside the parentheses: 4,25 - (2 7/9 * 3 3/5)

2. Perform the multiplication inside the parentheses first: 2 7/9 * 3 3/5 To multiply mixed numbers, convert them into improper fractions first: (29/9) * (18/5) Multiply the numerators and denominators separately: (29 * 18) / (9 * 5) 522 / 45

3. Now, subtract the result from the number outside the parentheses: 4,25 - (522 / 45)

4. Convert the whole numbers and fractions into improper fractions for easier calculation: 4,25 = 4 + 1/4 = (4 * 4 + 1) / 4 = 17/4

5. Perform the subtraction: 17/4 - (522 / 45)

To subtract fractions, the denominators must be the same. So, we need to find a common denominator for 4 and 45, which is 180.

6. Convert both fractions to have a denominator of 180: (17/4) * (45/45) = 765/180 (522/45) * (4/4) = 2088/180

7. Subtract the fractions: 765/180 - 2088/180 = (765 - 2088) / 180 = -1323/180

8. Simplify the result: -1323/180 = -737/100

So, the final result of the expression 17,25:(4,25-2 7/9* 3 3/5 is -737/100.
