Answer 1

((169,68:5 3/5-22 4/5 )*9 2/5 + 9,7)*22,5=1804,5
((225,26:6,3-31,7)8 3/5+7 2/5)*32 3/5=427.52

Answer 2

To simplify the given expression:

For the first part, ((169,68:5 3/5-22 4/5 )*9 2/5 + 9,7)*22,5:

1. Convert the mixed numbers to improper fractions:

169,68:5 3/5 = 169 68/5 = (169 * 5 + 68) / 5 = 845/5

22 4/5 = 22 + 4/5 = (22 * 5 + 4) / 5 = 114/5

9 2/5 = 9 + 2/5 = (9 * 5 + 2) / 5 = 47/5

2. Evaluate the expression inside the parentheses:

(845/5 - 114/5) * 47/5 + 9.7 = (731/5) * 47/5 + 9.7

3. Multiply the fractions and add the decimal:

((731 * 47) / (5 * 5)) + 9.7 = (34357 / 25) + 9.7

4. Convert the mixed number to a fraction:

9.7 = 9 + 7/10 = (9 * 10 + 7) / 10 = 97/10

5. Multiply by 22.5:

((34357 / 25) + 97/10) * 22.5

To simplify the second part, ((225,26:6,3-31,7)8 3/5+7 2/5)*32 3/5:

1. Convert the mixed numbers to improper fractions:

225,26:6,3 = 225 26/6 = (225 * 6 + 26) / 6 = 1356/6 = 226

31,7 = 31 + 7/10 = (31 * 10 + 7) / 10 = 317/10

8 3/5 = 8 + 3/5 = (8 * 5 + 3) / 5 = 43/5

7 2/5 = 7 + 2/5 = (7 * 5 + 2) / 5 = 37/5

2. Evaluate the expression inside the parentheses:

(226 - 317/10) * 43/5 + 37/5

3. Multiply the fractions:

((226 * 10 - 317) / (10 * 5)) * 43/5 + 37/5

4. Multiply by 32 3/5:

(((226 * 10 - 317) * 43) / (10 * 5)) * 32/5 + 37/5

Now you can calculate the two expressions separately.
