Question

(1 5/7-1)+(6 9/14-1/8)=​

Answer 1

Ответ:

7 13/56

Пошаговое объяснение:

1 5/7 - 1 = 5/7

6 9/14 - 1/8 = 6 36/56 - 7/56 = 6 29/56

5/7 + 6 29/56 = 6 40/56 + 29/56 = 7 13/56

Answer 2

To solve the expression (1 5/7 - 1) + (6 9/14 - 1/8), you can follow these steps:

Step 1: Simplify each of the fractions separately.

1 5/7 - 1 can be simplified as follows: 1 5/7 - 1 = (7/7 + 5/7) - 1 = (12/7) - 1

6 9/14 - 1/8 can be simplified as follows: 6 9/14 - 1/8 = (14/14 + 9/14) - (1/8) = (23/14) - (1/8)

Step 2: Find a common denominator for both fractions.

To add or subtract fractions, you need a common denominator. In this case, you can use 56 as the common denominator because it's the least common multiple of 7 and 8 (7 * 8 = 56).

Step 3: Convert both fractions to have a denominator of 56.

For (12/7) - 1: (12/7) * (8/8) = (96/56)

For (23/14) - (1/8): (23/14) * (4/4) = (92/56) (1/8) * (7/7) = (7/56)

So, the expression becomes: (96/56) + (92/56) - (7/56)

Step 4: Add and subtract the fractions.

(96/56) + (92/56) - (7/56) = (96 + 92 - 7) / 56

Step 5: Calculate the numerator.

96 + 92 - 7 = 181

Now, the expression becomes: 181/56

This is the simplified result of the expression (1 5/7 - 1) + (6 9/14 - 1/8).
