Пошаговое объяснение:

5/26 + 11/26 - 7/26 = 9/26 5 8/21 -2 3/21 + 1 5/21 = 4 10/21 1 - 15/17 = 2/17 6 4/11 - 3 7/11 = 2 7/11

Answer 3

1) To solve the expression 5/26 + 11/26 - 7/26, we can combine the numerators and keep the denominator the same.

The numerator becomes 5 + 11 - 7, which equals 9. The denominator remains 26.

Therefore, the expression simplifies to 9/26.

2) To solve the expression 5 + 8/21 - 2 + 3/21 + 1 + 5/213, we can combine the whole numbers and the fractions separately.

The whole numbers add up to 5 - 2 + 1, which equals 4.

The fractions have different denominators, so we need to find a common denominator. The least common multiple of 21 and 213 is 213.

Converting the fractions to have a denominator of 213, we get 8/21 = 32/84 and 3/21 = 9/63.

Now we can add the fractions: 32/84 + 9/63 + 5/213.

To add fractions, we need a common denominator. The least common multiple of 84, 63, and 213 is 12,852.

Converting the fractions to have a denominator of 12,852, we get:

32/84 = 4,032/10,656, 9/63 = 1,452/10,656, and 5/213 = 640/12,852.

Now we can add the fractions: 4,032/10,656 + 1,452/10,656 + 640/12,852.

Adding the numerators, we get 6,124/10,656 + 640/12,852.

To add fractions, we need a common denominator. The least common multiple of 10,656 and 12,852 is 136,512.

Converting the fractions to have a denominator of 136,512, we get:

6,124/10,656 = 82,944/136,512 and 640/12,852 = 8,640/136,512.

Now we can add the fractions: 82,944/136,512 + 8,640/136,512.

Adding the numerators, we get 91,584/136,512.

Therefore, the expression simplifies to 91,584/136,512, which can be further simplified if needed.

3) To solve the expression 1 - 15/174, we can subtract the fractions.

The denominator remains 174.

To subtract fractions, we need a common denominator. The least common multiple of 174 and 1 is 174.

Converting the fractions to have a denominator of 174, we get 15/174 = 15/174 and 1 = 174/174.

Now we can subtract the fractions: 174/174 - 15/174.

Subtracting the numerators, we get 159/174.

Therefore, the expression simplifies to 159/174, which can be further simplified if needed.

4) To solve the expression 6 + 4/11 - 3 + 7/11, we can combine the whole numbers and the fractions separately.

The whole numbers add up to 6 - 3, which equals 3.

The fractions have the same denominator, so we can add them directly.

Adding the fractions 4/11 and 7/11, we get 11/11, which simplifies to 1.

Therefore, the expression simplifies to 3 + 1, which equals 4.

In summary: 1) 5/26 + 11/26 - 7/26 = 9/26 2) 5 + 8/21 - 2 + 3/21 + 1 + 5/213 = 91,584/136,512 (or simplified if needed) 3) 1 - 15/174 = 159/174 (or simplified if needed) 4) 6 + 4/11 - 3 + 7/11 = 4
