Answer 1

Ответ:1 ) 15\28 - 11\36 = 58\252 = 29\126

2 ) 29\126 * 21\29 = 1\6

3 ) 6 6\7 : 16\21 = 48\7 * 21\16 = 9

4 ) 1\6 + 9 = 1\6 + 8 6\6 = 8 7\6

5 ) 8 7\6 : 16 1\2 = 55\6 : 33\2 = 55\6 * 2\33 = 55\99 = 5\9

Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Simplify the fractions within parentheses: (15/28 - 11/36) = (45/84 - 11/36) = (45/84 - 22/72) = (45/84 - 22/84) = 23/84

Step 2: Calculate the product of (23/84) and (21/24): (23/84) * (21/24) = (23 * 21) / (84 * 24) = 483/2016

Step 3: Simplify the fraction 6 6/7: 6 6/7 = (6 * 7 + 6) / 7 = 48/7

Step 4: Divide (483/2016) by (16/21): (483/2016) / (16/21) = (483/2016) * (21/16) = (483 * 21) / (2016 * 16) = 10143/64512

Step 5: Simplify the mixed number 16 1/2: 16 1/2 = (16 * 2 + 1) / 2 = 33/2

Step 6: Divide (10143/64512) by (33/2): (10143/64512) / (33/2) = (10143/64512) * (2/33) = (10143 * 2) / (64512 * 33) = 20286/2126976

Final Result: The value of the given expression is 20286/2126976.
