Answer 1

Ответ:

-1 19/63

Пошаговое объяснение:

1)3 1/7: 1 1/2= 2 2/21

2)4 2/7- 2 2/21= 4 6/21- 2 2/21= 2 4/21

3) 8/9- 2 4/21= - 1 19/63

Answer 2

Let's break down the expression step by step:

1. Start with the innermost parentheses:

   • 3 1/7 can be converted to an improper fraction: 3 + 1/7 = 22/7
   • 1 1/2 can be converted to an improper fraction: 1 + 1/2 = 3/2

2. Perform the subtraction inside the parentheses:

   • 4 2/7 - 22/7 = (4*7 + 2)/7 - 22/7 = (28 + 2)/7 - 22/7 = 30/7 - 22/7 = 8/7

3. Substitute the result back into the original expression:

   • 8/9 - 8/7

Now, we need to find a common denominator to subtract these fractions. The least common multiple of 9 and 7 is 63.

4. Rewrite the fractions with the common denominator of 63:

   • (8/9) * (7/7) = 56/63
   • (8/7) * (9/9) = 72/63

5. Perform the subtraction:

   • 56/63 - 72/63 = -16/63

So, the result of the expression 8/9 - (4 2/7 - 3 1/7) / (1 1/2) is -16/63.
