Answer 1

0.000000000000000000000000$

Answer 2

To solve the given expression, we'll perform the operations step by step:

1. Subtract 1 1/72 from 1 5/7: Convert both mixed numbers to improper fractions: 1 5/7 = (7 * 1 + 5)/7 = 12/7 1 1/72 = (72 * 1 + 1)/72 = 73/72

   Now, subtract: 12/7 - 73/72 To subtract fractions, find a common denominator, which is the least common multiple of 7 and 72, which is 504. Convert both fractions to have the denominator 504: (12/7) * (72/72) = 864/504 (73/72) * (7/7) = 511/504

   Now, subtract the fractions: 864/504 - 511/504 = (864 - 511)/504 = 353/504

2. Divide 2/3 by 3 17/21: Convert the mixed number to an improper fraction: 3 17/21 = (21 * 3 + 17)/21 = 80/21

   Now, divide: (2/3) ÷ (80/21) To divide by a fraction, multiply by its reciprocal: (2/3) * (21/80) = 42/240

   Simplify the fraction: 42/240 = 7/40

3. Subtract 11/14 from 3 1/7: Convert the mixed number to an improper fraction: 3 1/7 = (7 * 3 + 1)/7 = 22/7

   Now, subtract: 22/7 - 11/14 To subtract fractions, find a common denominator, which is the least common multiple of 7 and 14, which is 14. Convert both fractions to have the denominator 14: (22/7) * (2/2) = 44/14 (11/14) * (1/1) = 11/14

   Now, subtract the fractions: 44/14 - 11/14 = (44 - 11)/14 = 33/14

4. Add 30/493 to 2 1/7: Convert the mixed number to an improper fraction: 2 1/7 = (7 * 2 + 1)/7 = 15/7

   Now, add: 15/7 + 30/493 To add fractions, find a common denominator, which is the least common multiple of 7 and 493, which is 3449. Convert both fractions to have the denominator 3449: (15/7) * (493/493) = 7395/3449 (30/493) * (7/7) = 210/3449

   Now, add the fractions: 7395/3449 + 210/3449 = (7395 + 210)/3449 = 7605/3449

5. Add 1 1/9 to 1/3: Convert the mixed number to an improper fraction: 1 1/9 = (9 * 1 + 1)/9 = 10/9

   Now, add: 10/9 + 1/3 To add fractions, find a common denominator, which is the least common multiple of 9 and 3, which is 9. Convert both fractions to have the denominator 9: (10/9) * (1/1) = 10/9 (1/3) * (3/3) = 3/9

   Now, add the fractions: 10/9 + 3/9 = (10 + 3)/9 = 13/9

The final expression is: 353/504 : 7/40 : 33/14 : 7605/3449 : 13/9
